Question

What is the range of the function f(x)=7-3x when the domain is {-4, -2, 0, 2}?

Answer 1

{19,13,7,1}

Explanation:

Since the domain is the input we have to plug in each of those numbers to get the range ( or the output.) When we plug in -4 we get 19. When we plug in -2 we get 13, when we plug in 0 we get 7 and when we plug in 2 we get 1. (:
