Answer:
If h(x) is the inverse of f(x), then the value of h(f(x)) is x
Explanation:
If h(x) is the inverse of f(x) then we need to find h(f(x))
For example, lets take

Now we find inverse of f(x)

Replace x with y and y with x

Subtract 10 on both sides

Replace y with h(x)

now we need to find h(f(x))

If h(x) is the inverse of f(x), then the value of h(f(x)) is x
