Questions and Answers
  • 1. 

    Differentiate y=3x4-5x

    • A.

      3x3-5

    • B.

      12x3-5

    • C.

      12x3+5

    • D.

      12x2

    Correct Answer
    B. 12x3-5
    Explanation
    The correct answer is 12x3-5. This is the correct answer because when we differentiate the given function y=3x4-5x, we apply the power rule of differentiation which states that when differentiating a term with a variable raised to a power, we multiply the coefficient by the power and then decrease the power by 1. Therefore, when we differentiate 3x4, we get 12x3, and when we differentiate -5x, we get -5. Thus, the derivative of y=3x4-5x is 12x3-5.

    Is differentiation of y=6x3-1 is 18x3 true or false?

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The differentiation of y=6x^3-1 is not equal to 18x^3. When we differentiate y=6x^3-1, the power rule states that the derivative of x^n is nx^(n-1). Therefore, the derivative of 6x^3 is 18x^2, not 18x^3.

    Differentiate y=5/x2

    • A.

      5x2

    • B.

      -5x-3

    • C.

      -10x-3

    • D.

      10x-3

    • E.

      Option 5

    Correct Answer
    C. -10x-3
    Explanation
    The given expression is y = 5/x^2. To differentiate this expression, we use the power rule of differentiation. The power rule states that when differentiating a function of the form f(x) = x^n, the derivative is given by f'(x) = nx^(n-1). Applying this rule, we differentiate y = 5/x^2 as follows:
    y' = (5)(-2)x^(-2-1) = -10x^(-3) = -10/x^3. Therefore, the correct answer is -10x-3.

    Differentiate y= -3x-5-10x+2

    • A.

      3x5-10x

    • B.

      -3x-6+10

    • C.

      15x-6-10

    • D.

      15x-5-10

    Correct Answer
    C. 15x-6-10
    Explanation
    The given expression is a polynomial with two terms. To differentiate it, we can use the power rule, which states that the derivative of x^n is n*x^(n-1). Applying this rule to the first term, -3x, we get -3. For the second term, -10x, the derivative is -10. Therefore, the derivative of the given expression is 15x - 3 - 10, which simplifies to 15x - 6 - 10.

    Differentiate y=3x-4+6x-1

    • A.

      12x-1

    • B.

      -4x-5+6x-1

    • C.

      12x-5+6

    • D.

      -12x-5+6

    • E.

      Option 5

    Correct Answer
    D. -12x-5+6
    Explanation
    The given expression is y=3x-4+6x-1. We can simplify this expression by combining like terms. Combining 3x and 6x, we get 9x. Combining -4 and -1, we get -5. Therefore, the simplified expression is 9x - 5. The answer -12x-5+6 does not match the simplified expression, so it is not the correct answer.

  • 6. 

    Differentiate y=5-13x2-4x3

    • A.

      26x-12x

    • B.

      -26x-12x2

    • C.

      -13x2-12x

    • D.

      26x2-12

    • E.

      Option 5

    Correct Answer
    B. -26x-12x2
    Explanation
    The given expression is y=5-13x^2-4x^3. To differentiate this expression, we take the derivative of each term. The derivative of 5 is 0, the derivative of -13x^2 is -26x, and the derivative of -4x^3 is -12x^2. Therefore, the differentiated expression is -26x-12x^2.

  • 7. 

    Is differentiation of y=5x-2-12 is -10x-3 true or false?

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The given expression y=5x-2-12 can be simplified as y=5x-14. Therefore, the correct answer -10x-3 is false.

    Rate this question:

  • 8. 

    Differentiate y=4/x4

    • A.

      4x-5

    • B.

      4x5

    • C.

      16x-5

    • D.

      -16x-5

    Correct Answer
    D. -16x-5
    Explanation
    The given expression is y = 4/x^4 - 4x - 5. To differentiate this expression, we can use the power rule for differentiation. The derivative of 4/x^4 is -16/x^5, the derivative of -4x is -4, and the derivative of -5 is 0. Combining these derivatives, we get -16/x^5 - 4. Simplifying further, we can rewrite this as -16x^-5 - 4, which is equivalent to -16/x^5 - 4. Therefore, the correct answer is -16x - 5.
