Lol what...
Okay

f (-3) = 2x^2 - 6x + 11.
f (x) is f (-3) so minus 3 is x and the x's in the equation are x not multiply.
Idk how else to explain it lmao

Maybe it's just me but I'm still completely confused!

Can you please post a picture of the original question? And I still don't know what your answer was that you want us to check.
