Question

If f(x)=x²-1, which of the following ordered pairs are on the graph of f(x)? Select all that
apply.
(0,1)
(1,0)
(3,5)
(5,24)
(-2,3)
(-4,-17)

Answers

  1. The ordered pairs are on the graph of f(x) are (1, 0), (5, 24) and (-2, 3)

    How to determine the ordered pairs are on the graph of f(x)?

    The equation of the function is given as:
    f(x) = x^2 – 1
    Using the points in the options, we have
    f(0) = 0^2 – 1 = -1 — this is false
    f(1) = 1^2 – 1 = 0 — this is true
    f(3) = 3^2 – 1 = 8 — this is false
    f(5) = 5^2 – 1 = 24 — this is true
    f(-2) = (-2)^2 – 1 = 3 — this is true
    f(-4) = (-4)^2 – 1 = 15 — this is false
    Hence, the ordered pairs are on the graph of f(x) are (1, 0), (5, 24) and (-2, 3)
