Arely Whitehead · Answer 1

g (f (4))) = 9

Step-by-step explanation:

f (x) x-7

f (4) = 4-7=-3

g (f (4))) = (x-7) ^2>3^2=9

g (f (4))) = 9

Dereon Ferguson · Answer 2

9

Step-by-step explanation:

First evaluate f (4) then substitute the value obtained into g (x)

f (4) = 4 - 7 = - 3

g ( - 3) = ( - 3) ² = 9

⇒g (f (4)) = 9
