The answer is f(g(4)) = 9
Since f(x) = x - 7 and g(x) = x², to find f(g(4)), we first need to find f(g(x)).
We find this by substituting g(x) into f(x) by replacing x with g(x)
So, f(x) = x - 7
f(g(x)) = g(x) - 7
Since g(x) = x²,
Substituting the value of g(x) into the equation, we have
f(g(x)) = g(x) - 7
Replacing g(x) with x², we have
f(g(x)) = x² - 7
Now, substituting the value of x when x = 4, we have
f(g(4)) = 4² - 7
f(g(4)) = 16 - 7
f(g(4)) = 9
So, the answer is f(g(4)) = 9
