•Range reset
Range values are reset to their initial values by pressing during range
display.
The initial values are as follows.
Xmin : -3 .8 Ymin
Xmax : 3.8 Ymax
Xscl : 1 Yscl
(Reference)
Range settings are performed within programs using the following format:
S Xmin value, Xmax value, Xscl value, Ymin value, Ymax value, Yscl value
Up to six data items are programmed after the S command. When less than
six items are programmed, range setting is performed in the order from the be­
ginning of the above format.
■User generated function graphs
After performing range settings, user generated graphs can be drawn simply by
entering the function (formula) after pressing S .
Here, let’s try drawing a graph for y = 2 x 2 + 3 x - 4 .
Set the ranges to the values shown below.
Xmin : - 5 Ymin :
- 1 0
Xmax : 5 Ymax :
1 0
Xscl :

Yscl 4
Input the functional formula after pressing the S key.
