For each pair of functions f and g below, find fg (x)) and g(f(x)).
Then, determine whetherf and g are inverses of each other.
Simplify your answers as much as possible.
(Assume that your expressions are defined for all x in the domain of the composition.
You do not have to indicate the domain.)
(a) f(x) =
(b) f(x) = x + 2
9 (x) =
g(x)
= -x + 2
r(a (x)) = |
f(a (x)) = D
9(/(«)) = D
g(f(x)) = D
