See below.

Step-by-step explanation:

Graphically: the graphs of a function and its inverse are symmetric with respect to the line y = x.

Algebraically: If functions f (x) and g (x) are inverses of each other, then the composition of f and g must equal x, and the composition of g and f must also equal x.
