What is the range of the function f(x) = 3.2x for the domain {-4, -2, 0, 2, 4}?

Question

anonymous · Answer

Solve f(x) = 3.2x for each value in our domain
 
f(-4) = 3.2(-4) =
f(-2) = 3.2(-2) = 
f(0) = 3.2(0) =
f(2) = 3.2(2) =
f(4) = 3.2(4) =

so i just multiply 3.2 for each of the equations

ok i got that one but i need help with a second

What is the range of the function f(x) = 12 − 3x for the domain {-4, -2, 0, 2, 4}?

anonymous · Answer

Do the same. Just exchange plug in the domain in x.

Like, f(-4)=12-3(-4)

and so on.
