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

Basically what the function does is

f (x) = something

when you do inversee it is

f (x) turns into h (x)

when you do h (f (x)) that double reverses it and calncels it out to get x

a test to see if it is the inverse is to put it in and you should get x so

lets say

f (x) = x+5

inverse would be

h (x) = x-5

so

h (f (x)) = (x+5) - 5=x+5-5=x

answer is x
