Questions and Answers
  • 1. 

    Which of the following is true about the domain of a function?

    • A.

      It can be empty.

    • B.

      It must be positive.

    • C.

      It must be whole numbers.

    • D.

      It is always negative.

    Correct Answer
    A. It can be empty.
    Explanation
    The domain of a function can indeed be an empty set. This can happen when there are no valid inputs for which the function produces an output

    Rate this question:

  • 2. 

    If two functions have the same domain and their outputs are equal for every input, they are called:

    • A.

      Inverse functions

    • B.

      Identical functions

    • C.

      Parallel functions

    • D.

      Composite functions

    Correct Answer
    B. Identical functions
    Explanation
    If two functions have the same outputs for every input, they are considered identical functions

    Rate this question:

  • 3. 

    Find the range of the following function f(x) = 2x + 3?

    • A.

      All real numbers

    • B.

      Positive real numbers

    • C.

      Negative real numbers

    • D.

      Integers

    Correct Answer
    A. All real numbers
    Explanation
    The function f(x) = 2x + 3 is a linear function, and its range encompasses all real numbers

    Rate this question:

  • 4. 

    If a function passes the horizontal line test, it means:

    • A.

      It's a linear function.

    • B.

      It's a one-to-one function.

    • C.

      It's an odd function.

    • D.

      It's not a polynomial.

    Correct Answer
    B. It's a one-to-one function.
    Explanation
    Passing the horizontal line test indicates that the function is one-to-one, meaning that each input maps to a unique output

    Rate this question:

  • 5. 

    The composition of two functions f and g is denoted by:

    • A.

      F(x) * g(x)

    • B.

      F(g(x))

    • C.

      F / g

    • D.

      F + g

    Correct Answer
    B. F(g(x))
    Explanation
    The composition of two functions f and g is denoted by f(g(x)), which means applying the function g first and then applying f to the result

    Rate this question:

  • 6. 

    The function f(x) = x^2 is:

    • A.

      Linear

    • B.

      Odd

    • C.

      Even

    • D.

      Constant

    Correct Answer
    C. Even
    Explanation
    The function f(x) = x^2 is an even function because it is symmetric about the y-axis.

    Rate this question:

  • 7. 

    If f(x) = 3x + 2 and g(x) = x - 5, what is (f ∘ g)(x)?

    • A.

      2x - 3

    • B.

      4x - 3

    • C.

      3x - 7

    • D.

      3x - 3

    Correct Answer
    C. 3x - 7
    Explanation
    The composition (f ∘ g)(x) means applying function g first and then applying f In this case, it results in 3x - 7.

    Rate this question:

  • 8. 

    The point where a function intersects the y-axis is called the:

    • A.

      Origin

    • B.

      Vertex

    • C.

      Focus

    • D.

      Y-intercept

    Correct Answer
    D. Y-intercept
    Explanation
    The point where a function intersects the y-axis is known as the y-intercept.

    Rate this question:

  • 9. 

    If x is a set that contains an integer which is neither negative nor positive then the set x is 

    • A.

      Empty

    • B.

      Non-empty

    • C.

      Finite

    • D.

      Both Non- empty and Finite

    Correct Answer
    D. Both Non- empty and Finite
    Explanation
    The non-empty and finite set is set {0}.

    Rate this question:

  • 10. 

    The vertical line test is used to determine:

    • A.

      If a function is odd or even

    • B.

      If a function is continuous

    • C.

      If a function has a vertical asymptote

    • D.

      If a relation is a function

    Correct Answer
    D. If a relation is a function
    Explanation
    The vertical line test is used to determine whether a relation is a function. If any vertical line intersects the graph of the relation in more than one point, the relation is not a function.
