Question

Given the function f(x) = 4 - 2x: If the domain is {-4,0, 5), find the range.

A)
{-4, 4,-6)
B)
{-4, 4, 14)
C)
{12, 4, -6}
D)
{12, 4, 14)

Answer 1

C) -4,4,-6

Explanation:

domain is x so plug the domain numbers into the function

4-2(-4)=12

4-2(0)=4

4-2(5)=-6

Therefore Range is (-4,4,-6)
