Find the interval of increasing and decreasing of the given function

Answer to Problem 54RE
The graph is increasing on
Explanation of Solution
Given information: consider the function
Calculation:
Press the
Once this is done on the Window screen
X min =5
X max= 5
Y min = -5
Y max= 20
Adjust Xscl =1
This gives a rang that is good for many
Varied graph types
Set the window
Then click the GRAPH button.
For finding increase and decrease intervals, click the TRACE button and use the left and right buttons to find values.
So the graph is increase on
Thus, the graph is increasing on
