EL-9600 Graphing Calculator

Example

Before carrying out the following operation, press the reset switch located on the back of the unit and press

keys (caution: previously entered equations and memory will be erased).

Use substitute graph function to see how the shape of the graph

changes when different numbers are substituted for the variable.

Specify Rect mode on the screen.

Enter the graph equation

“AX

+BX

+C” at Y1.

As shown, Rect corresponds to

. The example shows

the initial settings of the EL-9600.

]

Specify substitute graph mode.

As shown, the left of the screen shows the

graph coordinate and the right of the screen

shows that input of the variable used in the

equation is being awaited.

]

Substitute 1 for variable A.

(On left of screen the graph “Y=1X

” is

displayed. B and C are presumed to be

“0” as numbers have not been entered.)

Substitute1 for variable B.

(On left of screen the graph

“Y=1X

+1X

” is displayed. C is pre-

sumed to be “0” as numbers have not

been entered).

Substitute -5 for variable C.

(On left of screen the graph

“Y=1X

+1X

-5” is displayed. Thus all

variables are substituted with numbers.)

Alter the numbers for variable B from 1

to 3 and view the changes in the graph.

(The graph equation is

Y=1X

+3X

-5).

Similarly, alter the numbers for variable

A from 1 to 0.5 and view the changes

in the graph.

(The graph equation is

Y=0.5X

+3X

-5).
