Question

F(x) = -x² + 6
Find f(-3).

Answer 1

Explanation:

f(-3)= -(-3)^2+6= -9 + 6 = -3

Answer 2

Explanation:

this is a really questuon so instead of x we put -3 so its going to look something like this. (PLUG IN -3 FOR X)

f(-3)= (-3)^2+6

f(-3)= -9+6 (-9 because of -3^2)

then the equation becomes

f(-3)= -9+6

(USING THE RULES) we get -3 as our Final answer
