k Specifying 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 = x
2
+ 3 x – 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
1 m Graph
