Revolt · Accepted Answer

h(x) = 3x - 6

Question 9

Which statements are true for the functions g(x) = x2 and h(x) = –x2 ? Check all that apply.

Revolt · Accepted Answer

For all non-zero values of x, g(x) will always be greater than h(x).; g(x) > h(x) for x = -1.; For positive values of x, g(x) > h(x).; For negative values of x, g(x) > h(x).
