Write the composite function in the form f(g(x)).
[Identify the inner function u = g(x) and the outer function y = f(u).]
(Use non-identity functions for f(u) and g(x).)
y=e^9 √x
Let u = g(x) = √x and y = f(u) = e^9u
Therefore, the composite function can be written as:
f(g(x)) = e^9√x
So, the inner function is u = g(x) = √x and the outer function is y = f(u) = e^9u.
