Explanation of Solution
Given information :
The functionsare
Prove : if
Now, substitute the x of function f by function
Thus, the functions are inverse function.
b.
To show : that
b.

Explanation of Solution
Given information :
The functions are
Prove : by using graphing utility, enter
x | ||
4 | 88.66 | |
5 | 211.67 | |
6 | 435.33 | |
7 | 803.66 |
By using these points and table, the graph can be obtained as:
Form the above graph it can be observed that the graph of both function is reflection in the line
Thus, the functions are inverse function.
c.
To show : that
c.

Explanation of Solution
Given information :
The functions are
Prove : to show the functions are inverse function numerically, by using a graphing utility.
Enter
8 | 8 | 8 |
9 | 9 | 9 |
10 | 10 | 10 |
11 | 11 | 11 |
12 | 12 | 12 |
From the table it can be observed that the entries for x ,
Thus, the functions are inverse function.
