Answer:
The value of the g(f(4)) is 9 .
Explanation:
As given the expression in the question be as follow.
f(x) = x − 7
g(x) = x²
Now find g(f(4)).
First find f(4) .
f(4) = 4 - 7
= -3
Thus
g(f(4)) = (-3)²
As
(-3)² = 9
Put in the above expression
g(f(4)) = 9
Therefore the value of the g(f(4)) is 9 .
