Setting a Viewing Rectangle

In order for a VIEWING RECTANGLE to be meaningful, a graph must already be displayed on the screen.  If you do not know how to enter and graph a function, go to Graphing a Function.  For example, the function = is graphed below in a standard VIEWING RECTANGLE, [-10,10,1] by [-10,10,1].
