Question

Use f(x) = 1 2 x and f -1(x) = 2x to solve the problems.
f(2) =
f−1(1) =
f−1(f(2)) =

Answer 1

Here is your answer,
f(2) = 12(2) = 24, f - 1(2) = 2(-2) = -4
f -1(1) = 12(-1) = -12, f - 1(-1) = 2(-1) = -2
f -1(f(2)) = 12(-2f) = -24f, f - 1(-2f) = 2(-2f)= -4f.

Answer 2

1. f(2)= 24
2. f-1(1)=2
