Can someone please help me with a few questions?

OpenStudy (anonymous):

f(x) = x^2+4,g(x) = 5x-3. (f o f) (x)

OpenStudy (anonymous):

(f o f) means you plug the f function back into itself. So f(x) = x^2 + 4. When you plug something into that function, it becomes (____)^2 + 4, with whatever you plug in going in those parentheses. Can you plug in the f function in that space?
