| ||||||
Calculation:
Graphing calculator to obtain the value of function
The value of the functions
| ||||||
Therefore,thevalues of the functions
(c)
The graph of the functions
(c)
Answer to Problem 81E
The graph of the functions
Explanation of Solution
Given information:
The given functions
Calculation:
Press
The screen look like as.
Press
Both the functions have the same value the graph coincide to each other.
Therefore, the graph of the functions
(d)
