Given
Now, let us sketch the graph of the two functions in the interval
To plot both the graph together on same axis, follows the steps given below:
Press the button
Press the button WINDOW and adjust the window as shown:
Press the button TRACE or GRAPH to obtain the graph.
Now, press the button 2nd CALC. Select option “5”
Move cursor on to
Now move cursor on to
Move cursor near point of intersection of graph on right and press ENTER
It will show following coordinates.
Repeat above procedure to find point of intersection on left.
It will show following coordinates.
Hence,
