3. Drawing a Graph
You can store up to 20 functions in memory. Functions in memory can be edited, recalled, and
graphed.
k
Specifying the Graph Type
Before you can store a graph function in memory, you must first specify its graph type.
1. While the graph relation list is on the display, press
3
(TYPE) to display the graph type
menu, which contains the following items.
• { Y= } / { r= } / { Param } / { X= } ... {rectangular coordinate (Y=
f
(
x
) type)}/{polar coordinate}/
{parametric}/{rectangular coordinate (X=
f
(
y
) type)} graph
• { Y> } / { Y< } / { Y
≥
} / { Y
≤

... {changes the function type of the selected expression}
2. Press the function key that corresponds to the graph type you want to specify.

• A function cannot be stored into a memory area that already contains a function of a different
type from the one you are trying to store. Select a memory area that contains a function that
is the same type as the one you are storing, or delete the function in the memory area to
which you are trying to store.
