    What is the integral of 1 with respect to x?

    • 0.5x

    • X + C

    • 1.25x

    • 2x

    Correct Answer
    A. X + C
    Explanation
    The integral of 1 with respect to x is x + C, where C is the constant of integration. The integral of a constant, such as 1, with respect to a variable, in this case, x, is simply the constant multiplied by x. Therefore, the integral of 1 with respect to x results in x. The constant C represents an arbitrary constant that can be added to the result because there are infinitely many antiderivatives of a function. This is the fundamental concept in indefinite integration.

    What is the derivative of xĀ² + 1 with respect to x?

    • 2x

    • X

    • X+1

    • 2x+1

    Correct Answer
    A. 2x
    Explanation
    The derivative of xĀ² + 1 with respect to x is 2x. Using the power rule, the derivative of xĀ² is 2x, and the constant term 1 has a derivative of 0. This is because the derivative of any constant is zero. Therefore, when differentiating the sum of xĀ² and 1, only the term with x (xĀ²) contributes to the derivative. As a result, the correct derivative of the given function is 2x.

    What is the derivative of the function f(x) = 1963?

    • 0

    • 1963

    • −∞

    • None of the above

    Correct Answer
    A. 0
    Explanation
    The derivative of a constant function is always 0. In this case, the function f(x) = 1963 is a constant because it does not depend on x. The derivative of a constant function is 0, as there is no change in the value of the function as x changes. The derivative measures the rate of change, and since there is no change in the function, the rate of change is zero. Thus, the derivative of f(x) = 1963 with respect to x is 0.

    What is the derivative of cos(x) with respect to x?

    • -sin(x)

    • Sin(x)

    • Cos(x)

    • -cos(x)

    Correct Answer
    A. -sin(x)
    Explanation
    The derivative of cos(x) with respect to x is -sin(x). This is a standard result from differentiation, derived from the fundamental trigonometric identities. The derivative of the cosine function describes the rate of change of the cosine curve at any point. When you differentiate cos(x), you are essentially calculating how fast the value of cos(x) is changing with respect to x. The result is -sin(x) because the graph of cos(x) slopes downward as x increases, which is why the derivative has a negative sign. This represents the rate of decrease of the cosine function.

    What is the derivative of f(x) = 3xĀ² + 4x - 1 with respect to x?

    • 6x + 4

    • 3x^2 + 4x

    • 6x + 4x - 1

    • 6x - 4

    Correct Answer
    A. 6x + 4
    Explanation
    To find the derivative of f(x) = 3xĀ² + 4x - 1, apply the power rule. The derivative of 3xĀ² is 6x (because 2 * 3 = 6). The derivative of 4x is 4 (since the derivative of x is 1). The constant term -1 has a derivative of 0. Combining these, the derivative of the function is 6x + 4. This represents the rate of change of the function f(x) = 3xĀ² + 4x - 1 with respect to x, indicating how the function behaves as x changes.

    State whether the given statement is true or false. The second fundamental theorem of calculus states that if F(x) = āˆ« ax f(t) dt then F '(x) = f(x). 

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The second fundamental theorem of calculus states that if F(x) is defined as the integral of a function f(t) with respect to t from a constant a to a variable x, then the derivative of F(x) with respect to x is equal to the integrand f(x). This theorem establishes a connection between differentiation and integration. It shows that the derivative of the accumulated area under the curve described by f(t) from a to x is simply the function value at x, making differentiation and integration inverse operations.

    Does the limit of the expression 'x - 1' exist as x approaches zero?

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The limit of the expression 'x - 1' as x approaches zero does exist. As x gets closer to zero, the expression x - 1 simply approaches -1. The limit describes the value that a function approaches as the input (x) approaches a particular value. In this case, as x approaches 0, the expression 'x - 1' approaches -1, so the limit exists and equals -1. Since there are no discontinuities or undefined points in this expression, the limit is well-defined and exists as x approaches zero.

    What is the integral of 2x with respect to x?

    • XĀ² + C

    • XĀ²

    • 2x + C

    • 2xĀ² + C

    Correct Answer
    A. XĀ² + C
    Explanation
    The integral of 2x with respect to x is solved by applying the power rule for integration, which states that the integral of xāæ with respect to x is (xāæāŗĀ¹)/(n+1) + C. For 2x, n = 1. Applying the rule, the integral is (2xĀ²)/2 + C, which simplifies to xĀ² + C. The constant C represents the constant of integration and accounts for the fact that there are infinitely many antiderivatives of a function, differing by a constant value. Thus, the result is xĀ² + C, where C is arbitrary.

    Which function, when integrated, produces the graph shown? - ProProfs

    Which function, when integrated, produces the graph shown?

    • -x+1

    • X-1

    • (x+1)

    • 2x

    Correct Answer
    A. 2x
    Explanation
    The graph described is a straight line with a positive slope, passing through the origin. The function that produces such a graph when integrated is 2x. When you integrate 2x with respect to x, the result is xĀ², which is a parabolic graph. A linear function with a positive slope like 2x produces a graph where the value of the function increases steadily as x increases. Thus, integrating 2x produces a graph that matches the description of a straight line with a positive slope.

    What is the limit of 1/(x - 1) as x approaches infinity?

    • Infinity

    • 0

    • -1

    • Negative infinity

    Correct Answer
    A. 0
    Explanation
    As x approaches infinity, the expression 1/(x - 1) behaves in such a way that the denominator becomes very large, making the entire fraction approach zero. As x increases, the term (x - 1) grows larger, and since the numerator remains constant at 1, the fraction becomes smaller and smaller. Therefore, the limit of 1/(x - 1) as x approaches infinity is 0. This is a standard result for rational functions where the degree of the denominator exceeds that of the numerator.

    Who are the two men credited with the discovery of calculus?

    • Newton

    • Gottfried Wilhelm Leibniz

    • Thomas Edison

    • Georg Cantor

    Correct Answer(s)
    A. Newton
    A. Gottfried Wilhelm Leibniz
    Explanation
    Isaac Newton and Gottfried Wilhelm Leibniz are both credited with independently developing the field of calculus. Newton, an English mathematician and physicist, developed calculus in the context of his work on physics and motion. Leibniz, a German mathematician, developed calculus using a different notation, which is still in use today. Though their discoveries were separate, both menā€™s contributions were crucial to the development of calculus. The dispute over who invented calculus first led to significant debates, but both Newton and Leibniz's work remains fundamental in mathematics.

    What is the derivative of xĀ² + 1 with respect to y?

    • 2x

    • Xy +1

    • 0

    • (x+1)y

    Correct Answer
    A. 0
    Explanation
    The expression xĀ² + 1 does not contain the variable y. When differentiating with respect to a variable that does not appear in the expression, such as y, the result is always 0. The derivative represents the rate of change of the function with respect to the variable, and if the function does not depend on that variable, the rate of change is zero. Therefore, the derivative of xĀ² + 1 with respect to y is 0, as there is no change in the function with respect to y.

    What is the limit of sin(x)/x as x approaches 0?

    • 0

    • 1

    • Undefined

    • Infinity

    Correct Answer
    A. 1
    Explanation
    The limit of sin(x)/x as x approaches 0 is a well-known result in calculus, and its value is 1. This can be shown using L'Hopital's Rule or by using the Taylor series expansion of sin(x). As x approaches 0, both the numerator and denominator approach 0, forming an indeterminate 0/0 form. By applying L'Hopital's Rule, we differentiate the numerator and denominator. The derivative of sin(x) is cos(x), and the derivative of x is 1. Thus, the limit becomes cos(0)/1, which equals 1.

    What is the second derivative of 4xā“ + 3xĀ² with respect to x?

    • 12xĀ³ + 6x

    • 12xĀ³ + 6x + 3

    • 16xĀ³ + 6x

    • 12xĀ³ + 3x

    Correct Answer
    A. 12xĀ³ + 6x
    Explanation
    To find the second derivative of 4xā“ + 3xĀ², we first differentiate the function once. The derivative of 4xā“ is 16xĀ³, and the derivative of 3xĀ² is 6x. Therefore, the first derivative is 16xĀ³ + 6x. Differentiating this again gives the second derivative. The derivative of 16xĀ³ is 48xĀ², and the derivative of 6x is 6. Thus, the second derivative is 48xĀ² + 6, which describes the rate of change of the rate of change of the function. This second derivative indicates how the curvature of the graph behaves at any point.
