Question

I just need the answer quickly. I've been stuck on this problem for ten minutes.

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

"the domain is {-4, 0, 5}"

so they give you the x values x = -4, x = 0, x = 5

you plug each of these x values one at a time into f(x) and evaluate

Answer 2
