Revolt · Accepted Answer

h(x) = 3x - 6

Question 7

Which statements are true for the functions g(x) = x2 and h(x) = –x2 ? Check all that apply.For all non-zero values of x, g(x) will always be greater than h(x).For all non-zero values of x, h(x) will always be greater than g(x).g(x) > h(x) for x = -1. g(x) h(x). For negative values of x, g(x) > h(x).
