For The Function F(x)= -x^2 +2 , Find F(3) And F(-4)(adsbygoogle = window.adsbygoogle || []).push({});

This Is My Work:

F(3) = -(3)^2 + 2

3= -9 + 2

3= -7

(Then I Divided 3 From Both Sides)

= -2.3

F(-4)= -(-4)^2 + 2

-4= -14

(Then I Divided -4 From Both Sides)

= 3.5

Am I Doing This Right?...
