• You must specify two different points for box zoom, and the two points cannot be on a

straight line vertically or horizontally from each other.

3. Drawing a Graph

You can store up to 20 functions in memory. Functions in memory can be edited, recalled, and

graphed.

I 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 (TYPE) to display the graph type

menu, which contains the following items.

•{Y=}/{r=}/{Parm}/{X=} ... {rectangular coordinate (Y=

f(x) type)}/{polar coordinate}/

{parametric}/{rectangular coordinate (X=

f(y) type)} graph

•{Y>}/{Y<}/{YP}/{YO} ... {Y>

f (x)}/{Y<f (x)}/{YPf (x)}/{YOf (x)} inequality graph

•{X>}/{X<}/{XP}/{XO} ... {X>

f(y)}/{X<f(y)}/{XPf(y)}/{XOf(y)} inequality graph

•{CONV}

•{

Y=}/{Y>}/{Y<}/{YP}/{YO}/{X=}/{X>}/{X<}/{XP}/{XO}

... {changes the function type of the selected expression}

2. Press the function key that corresponds to the graph type you want to specify.

I Storing Graph Functions

S To store a rectangular coordinate function (Y=)

Example To store the following expression in memory area Y1: y = 2x

– 5

(TYPE)(Y=) (Specifies rectangular coordinate expression.)

ATVD(Inputs expression.)

U (Stores expression.)

• 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.
