The only thing we need to here to find who is correct is evaluate the function
f(x)=-2 x^(2) +32 at
x=3. To do that we are going to replace
x with
3 in the function:

f(x)=-2 x^(2) +32

f(3)=-2 (3)^(2) +32

f(3)=-2 (9) +32

f(3)=-18+32

f(3)=14

We can conclude that Lynn is correct.
f(3) is indeed 14.
