You can put this solution on YOUR website!
f(0) = 2(0)^2 - 2(0) = 0 - 0 = 0
f(-1) = 2*(-1)^2 - 2(-1) = 2*1 + 2 = 4
f(2) = 2*(2)^2 - 2(2) = 8 - 4 = 4

You are correct on the first and third answers.
On the second one, it goes like this:
f%28-1%29+=+2%28-1%29%5E2-2%28-1%29
f%28-1%29+=+2%281%29-%28-2%29
f%28-1%29+=+2%2B2
f%28-1%29+=+4
