(
for each pair of functions f and g below, find f (g(x)) and g
then, determine whether f 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) = 2x
8(x) = 2x + 5
g(x) = 2x
xs ?
f(g(x)) = 0
f($(x)) = 0
8v(x)) = 0
8((x) =
0
f and g are inverses of each other
f and g are not inverses of each other
f and g are inverses of each other
f and g are not inverses of each other
