25 I'm guessing because half of 50 IS 25. So 25 sq m should be the answer.

lynn, jude and anne were given the function f(x)=-2x^2+32, and they were asked to find f(3). lynns answer was 14, judes answer w

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.
