find the indicated outputs for f(x)=3x^2-5x

Question

I get

f(0)=0
f(-1) = 1
f(2) =8)
am I doing this right if not could you explain where I am wrong.

Answer 1

yes, no ...3(-1)62-5(-1)=3+5=2
and finally, no. Rework that. What is 3*4-10?

Answer 2

This would be 2 but how can f(2)=2

Answer 3

yes, f(2)=2. 3*2^2-5*2=12-10=2
