Pressing (SEL) while one of the function’s 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).

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

IRectangular Coordinate Graph

Inputting the Graph command in the RUN • MAT (or RUN) mode enables drawing of rectangular coordinate graphs.

1.From the Main Menu, enter the RUN • MAT (or RUN) mode.

2.Make V-Window settings.

3.Input the commands for drawing the rectangular coordinate graph.

4.Input the function.

Example

Graph y = 2x2 + 3x – 4.

 

Use the following V-Window settings.

Xmin = –5,

Xmax = 5,

Xscale = 2

Ymin = –10,

Ymax = 10,

Yscale = 5
