find f(2). I got f(2) = (-9) ... it's -7
find f(-3). I got f(-3) = (-42) ... it's 18
I think you have to recheck your signs in answer.
If f(x) = 2x^ - 7x +3
find f(2). I got f(2) = (-9)
find f(-3). I got f(-3) = (-42)

PS, if you meant 2x square root of 2, the answers would be different

f(2) = -3
f(-3) = 42
