uTo recall V-Window memory settings

1. From the Main Menu, enter the Graph mode.

2. Press !3(V-WIN) to display the V-Window setting screen.

3. Press 4(V-MEM)2(RECALL) to display the pop-up window.

4. Press a number key to specify the V-Window memory number for the settings you want to recall, and then press w. Pressing bw recalls the settings in V-Window Memory 1 (V-Win1).

kSpecifying the Graph Range

You can define a range (start point, end point) for a function before graphing it.

1. From the Main Menu, enter the Graph mode.

2. Configure V-Window settings.

3. Specify the function type and input the function. The following is the syntax for function input.

Function ,!+( [ ) Start Point , End Point !-( ] )

4. Draw the graph.

Example	Graph y = x2 + 3x – 2 within the range – 2 < x < 4.
	Use the following V-Window settings.
	Xmin = –3,	Xmax = 5,	Xscale = 1
	Ymin = –10,	Ymax = 30,	Yscale = 5
