To 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 3 + 1, x 2 + x into function memory, and then graph:
y = x 3 + x 2 + x + 1
Use the following View Window parameters.
Xmin = –4 Ymin = –10
Xmax = 4 Ymax = 10
Xscale = 1 Yscale = 1
