Answer:
Explanation:
Your options for solutions are nonsensical. We'll go about this a different way...namely, I'll tell you about a function and its inverse and then you can pick the answer from your options, as best as it will fit.
If f(x) = x + 1 and f(x) is the same thing as y, you can say that y = x + 1
If h(x) is the inverse of f(x), we have to find what h(x) is. The way to do that is to switch the x and y coordinates in f(x) and solve for the new y.
f(x) = y = x + 1 then x = y + 1 and y = x - 1.
That tells us the inverse of f(x), aka h(x). If we then take the composition of f(x) into h(x) we will find its value.
h(f(x)) ---> h(x + 1) = (x + 1) - 1 and
h(f(x)) = x
This will ALWAYS BE TRUE, NO MATTER WHAT FUNCTION YOU PLUG IN.
Fact: the composition of an inverse into its function = x
