The Xscl and Yscl values on WINDOW set the scale for each of the axes. These numbers tell

the increment for placing tick marks on the axes. On the graph shown, the Xscl is 1 and the

Yscal is 10, so every mark along the x axis is 1 unit and every mark along the y axis indicates 10

units. With a scale of 0, the graph will display no tick marks.

Example: Graph the function entered at Y2.

First, go to Y= to turn off Y1 and turn on Y2.

Press GRAPH .

The WINDOW is still set for the function entered at Y1. To return to the standard viewing

window, press ZOOM, 6 .

More detail in quadrant 2 is needed, and more of the quadrant 4 portion of the graph should be

displayed. Unfortunately, it may not be possible to get a good view of the entire graph on one

window. Change the viewing window to [-20, 12, -8, 5] and check the result. Change Xscl to 4

and Yscl to 5.
