Question

do I have the right answers?


f(x) = (5 - x)²

Find f(2) and f(-2)

I end up with 24 on both equations

Answer 1

24 cannot be right, since f(x) is a perfect square if x is an integer.

f(2)=(5-2)²=?
f(-2)=(5-(-2))²=(7)²=?

Answer 2

Your answer of 24 is incorrect for both cases

f(x) = (5-x)^2
f(2) = (5-2)^2 = 3^2 = 9
f(-2) = (5-(-2))^2 = 7^2 = 49
