Answer:
Step-by-step explanation:
Given the below functions;

a) We're to find f(g(x)).
To do this, we need to substitute x in f(x) with g(x) as shown below;

b) To find g(f(x)), we need to substitute x in g(x) with f(x);

c) Since f(g(x)) = g(f(x)) = x, therefore f and g are inverses of each other.
Yes, f and g are inverses of each other.
So to
