  1. Which graph represents a non-linear function?

    Answer: A U-shaped parabola

    A U-shaped parabola represents a quadratic function, which is non-linear because its graph curves rather than forming a straight line.

  2. The range of a function refers to:

    Answer: The set of all possible output values

    The range is the complete set of possible output values (y-values) that a function can produce.

  3. What is the x-intercept of the function f(x) = 2x − 6?

    Answer: 3

    Set f(x) = 0: 0 = 2x − 6, so 2x = 6 and x = 3.

  4. If g(x) = 5 for all values of x, what type of function is g?

    Answer: Constant

    A function that outputs the same value for every input is a constant function; g(x) = 5 always equals 5 regardless of x.

  5. Two functions are defined as f(x) = x + 3 and g(x) = 2x − 1. For what value of x are f(x) and g(x) equal?

    Answer: x = 4

    Set x + 3 = 2x − 1, then 4 = x, so the functions are equal when x = 4.

  6. A linear function passes through the points (0, 5) and (2, 9). What is the slope?

    Answer: 2

    Slope = (9 − 5) / (2 − 0) = 4 / 2 = 2.

  7. Which of the following correctly describes function notation f(x)?

    Answer: The function f evaluated at input x

    f(x) is read 'f of x' and means the value of function f when the input is x; it is not multiplication.
