Answer:
Step-by-step explanation:
If we are looking to find the composition of g(f(4)), we start at the innermost part of the problem which is to evaluate f(4).
If f(x) = x - 7, then f(4) = 4 - 7. f(4) = -3.
Now take that -3 and evaluate the g(-3).
If g(x) = x^2, then g(-3) = (-3)^2 which is 9.
Therefore, f(g(4)) = 9
