Answer to Problem 7.2.17EP
The pair of functions
Explanation of Solution
Given information:
The functions
Formula used:
The composition of two functions f and gis
The two functions f and g are said to be inverse functions if and only if
Calculation:
Consider the functions
Recall that the composition of two functions f and gis
Therefore,
Simplify it further as,
And,
Similarly,
Recall that the two functions f and gare said to be inverse functions if and only if
Since,
