Example

Store the two functions below, generate a number table, and then draw

 

a line graph. Specify a range of –3 to 3, and an increment of 1.

 

Y1 = 3x2 – 2, Y2 = x2

 

 

Use the following V-Window settings.

 

Xmin = 0,Xmax = 6,

Xscale = 1

 

Ymin = –2,

Ymax = 10,

Yscale = 2

•You can use Trace, Zoom, or Sketch after drawing a graph.

•You can use the graph screen to change the properties of a graph after you draw using a number table. For details, see “To change graph properties from the graph screen” (page 5-16).

kSimultaneously Displaying a Number Table and Graph

Specifying “T+G” for “Dual Screen” on the Setup screen makes it possible to display a number table and graph at the same time.

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

2. Configure V-Window settings.

3. On the Setup screen, select “T+G” for “Dual Screen”.

4. Input the function.

5. Specify the table range.

6. The number table is displayed in the sub-screen on the right.

7. Specify the graph type and draw the graph.

5(GPH-CON) ... line graph

6(GPH-PLT) ... plot type graph
