Find the indicated outputs for f(x) = 2x²-4x

Question

f(0)= ____?
f(-1) =____?
f(2) =____?

Answer 1

f(0) = 2(0)^2 - 4(0)
= 0*0
= 0

f(-1) = 2(-1)^2 - 4(-1)
= 2(1) + 4
= 2 + 4
= 6

now you try f(2) the same way.

Answer 2

Reiny
I'm still lost
i only got so far.
f(2)=2(2)^2-4(2)
=2(2) from their on i'm lost please help
