Answer:


f(x) = (5)/(x)


g(x) = x - 4

Explanation:

Composite function:


h(x) = f(g(x)) = (f \circ g)(x)

h(x) = 5/x-4

We have x on the denominator and not the numerator, so the outer function is given by:


f(x) = (5)/(x)

The denominator is x - 4, so this is the inner function, so:


g(x) = x - 4
