Answer:
Suppose f and g are two functions such that
1. (g ◦ f)(x) = x for all x in the domain of f and
2. (f ◦ g)(x) = x for all x in the domain of g
then f and g are said to be inverses of each other. The functions f and g are said to be
invertible.
. Properties of Inverse Functions: Suppose f and g are inverse functions.
• The rangea of f is the domain of g and the domain of f is the range of g
• f(a) = b if and only if g(b) = a
• (a, b) is on the graph of f if and only if (b, a) is on the graph of g
