Use f(x) = 2 x and f-'(x) = 2x to solve the problems.
f(2)=
f1 (1) =
f1 (12)) =

a) 1

b) 2

c) 2

Step-by-step explanation:

a) means find the output for when .

b) means find the output for when

c) If and are truly inverses then and as long as satisfies the domains.

So we should be able to conclude that with no work.

However, I will also show work.

   since     from part a.

           since     from part b.
