Questions and Answers
  • 1. 

    The graph of a polynomial function is tangent to its?

    • A.

      Axis

    • B.

      Y-axis

    • C.

      X-axis

    • D.

      Orbit

    Correct Answer
    C. X-axis
    Explanation
    The graph of a polynomial function is tangent to its x-axis because when a polynomial function is tangent to the x-axis, it means that the function intersects the x-axis at exactly one point and does not cross it. This occurs when the polynomial function has a root or zero, which is a value of x that makes the function equal to zero. Therefore, the graph of the polynomial function will touch the x-axis at this root, resulting in a tangent.

    What do you call a polynomial with two as the highest degree 4?

    • A.

      Linear

    • B.

      Quadratic

    • C.

      Ellipse

    • D.

      Focal point

    Correct Answer
    B. Quadratic
    Explanation
    A polynomial is an algebraic expression with multiple terms. The highest degree in a polynomial refers to the exponent of the term with the highest power. In this case, the polynomial has a highest degree of 4, which means the term with the highest power is x^4. A quadratic polynomial is a polynomial with a highest degree of 2, so it does not fit the description given. Therefore, the correct answer is quadratic.

    Rate this question:

  • 8. 

    What is the degree of this given, x+2=0?

    • A.

      0

    • B.

      1

    • C.

      2

    • D.

      3

    Correct Answer
    B. 1
    Explanation
    The degree of a given equation is determined by the highest power of the variable present in the equation. In this case, the equation x+2=0 is a linear equation, meaning it has a degree of 1. The highest power of the variable x is 1, as there is no x^2 or any higher power term present in the equation. Therefore, the degree of the given equation x+2=0 is 1.

    Rate this question:

  • 9. 

    Which is a polynomial of degree 1?

    • A.

      X+1

    • B.

      5+5

    • C.

      Polynomial has no degree 1

    • D.

      Quadratic

    Correct Answer
    A. X+1
    Explanation
    The expression "x+1" is a polynomial of degree 1 because it consists of a variable (x) raised to the power of 1 (degree 1) and a constant term (1). The other options, "5+5", "polynomial has no degree 1", and "quadratic", do not meet the criteria of being a polynomial of degree 1.

    Rate this question:

    • C.

      25

    • D.

      30

    Correct Answer
    C. 25
    Explanation
    The constant term in an equation is the term that does not contain any variables. In the equation x+25, the constant term is 25 because it does not have any variable attached to it.

    How do you define the maximum number of roots in a polynomial?

    • A.

      Equal to the highest degree of a polynomial

    • B.

      Given by the polynomial

    • C.

      Multiplicity

    • D.

      By the number of roots

    Correct Answer
    A. Equal to the highest degree of a polynomial
    Explanation
    The maximum number of roots in a polynomial is determined by the highest degree of the polynomial. The degree of a polynomial represents the highest power of the variable in the polynomial expression. Since each root of a polynomial corresponds to a factor of the polynomial, the maximum number of roots can be equal to the degree of the polynomial.

      Linear

    • C.

      Cubic

    • D.

      Bi-quadratic

    Correct Answer
    D. Bi-quadratic
    Explanation
    A four-degree polynomial is called a bi-quadratic polynomial. This is because the prefix "bi-" means two, and a bi-quadratic polynomial has two quadratic terms.

    Rate this question:

  • 15. 

    What are the roots of G(x)= (x+2)(x-5)(x-1)?

    • A.

      -2,5,1

    • B.

      1,2,3

    • C.

      4,7,5

    • D.

      X,x,x

    Correct Answer
    A. -2,5,1
    Explanation
    The roots of a polynomial are the values of x that make the polynomial equal to zero. In this case, the polynomial G(x)=(x+2)(x-5)(x-1) will be equal to zero when any of the factors (x+2), (x-5), or (x-1) are equal to zero. By setting each factor equal to zero and solving for x, we find that the roots are x=-2, x=5, and x=1. Therefore, the correct answer is -2, 5, 1.

    Rate this question:

  • 16. 

    Is the graph of the polynomial function smooth?

    • A.

      Yes, and broken

    • B.

      Yes, continuous, and straight

    • C.

      Yes, continuous, and curve

    • D.

      No

    Correct Answer
    C. Yes, continuous, and curve
    Explanation
    The graph of a polynomial function is smooth because it is continuous and has no breaks or jumps. Additionally, the graph of a polynomial function is typically curved, as it can have various shapes such as parabolas, cubic curves, or higher-degree curves. Therefore, the correct answer is "yes, continuous, and curve."

    Rate this question:

  • 17. 

    How do you define the turning points of the graph of polynomial functions?

    • A.

      (n-1)180

    • B.

      N+1

    • C.

      N-1

    • D.

      N+2

    Correct Answer
    C. N-1
    Explanation
    The turning points of a graph of a polynomial function are defined as the points where the graph changes direction from increasing to decreasing or vice versa. In this case, the correct answer is n-1, which suggests that the number of turning points in the graph is equal to n-1. This means that the graph will have one less turning point than the degree of the polynomial function.
