uTo use stored functions

Once you store a function in memory, you can recall it and use it for a calculation.

This feature is very useful for quick and easy input of functions when programming

or graphing.

Example To store x

+ 1, x

+ x into function memory, and then graph:

y = x

+ x

+ x + 1

Use the following View Window parameters.

Xmin = –4 Ymin = –10

Xmax = 4 Ymax = 10

Xscale = 1 Yscale = 1
