Casio fx-CG20 Xscale, Yscale, Xscale, Yscale, Example, Xmax = 2, Ymax = 2, Xmax = 4, Ymax = 3, Xmin = –2, Ymin = –2, Xmin = –4, Ymin = –3

Pressing 1(SELECT) while one of the functions marked “ R ” or “ B ” is highlighted would causes its “ R ” or “ B ” indicator to be cleared. A function without an indicator is drawn as the main screen graph (on the left side of the display).

•The graph properties operation can be performed only for the graph that is on the left side of the Dual Graph graph screen.

•If you change the graph properties of an expression marked with “ B ” on the graph relation list screen and then draw the graph, the changes will be applied to both graphs.

•You cannot change the graph properties of an expression marked with “ R ” on the graph relation list screen.

•For details about how to change graph properties, see “Changing Graph Properties” (page 5-15).

Example	Graph y = x(x + 1)(x – 1) in the main screen and sub-screen.
	Use the following V-Window settings.
	(Main Screen)	Xmin = –2,	Xmax = 2,	Xscale = 0.5
		Ymin = –2,	Ymax = 2,	Yscale = 1
	(Sub-screen)	Xmin = –4,	Xmax = 4,	Xscale = 1
		Ymin = –3,	Ymax = 3,	Yscale = 1
