Answer: 2

Step-by-step explanation:

F(x)= X-5

G(x) =X2 +3

Find F(g(-2))

G(x)= x2 +3

G(x)=G(-2);

X= -2

Substitute for x in g equation

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

=4+3

=7

Therefore G(-2)= 7

F(g(-2))= x-5

Substitute for g(-2)= 7

F(7) = 7-5

=2

Answer:

= 2

Step-by-step explanation:

# g(x) = x^2 + 3 hence g(-2) = (−2)2+3=4+3=7

and so f(g(-2)) = f(7) = 7 - 5 = 2
