In this problem, we are given the following functions:
and its inverse function:
First of all, we want to calculate . This can be obtained by substituting
x = 2
into f(x). Doing so, we find:
Then we want to calculate . We can do it by substituting
x = 1
into . Doing so,
Then we want to calculate , which can be found by calculating f(2) and then using it as input for
We know that
f(2) = 1
Therefore,
Then we want to calculate , which can be calculated by plugging
x = -2
into . Doing so,
Then we want to calculate ; by substituting
x = 4
into f(x), we find
Finally, we want to find
We know already that
So we have:
