Answer:
Answer: 5
Explanation:
Remark
Start with the meaning of g[f(x)]. This when you write g(x), where ever you see and x in g(x), put in an f(x)
g(f(x))
g(x)= x + 1 Substitute f(x) for x
g(f(x)) = f(x) + 1 Substitute x^2 for f(x)
g(f(x)) = x^2 + 1
g(f(-2)) = (-2)^2 + 1 Substitute -2 for x
g(f(-2)) = (4) + 1
g(f(-2)) = 5 Answer
