Graph Function Operations - Casio CFX-9850G PLUS Graphing Manual

8-3 Graph Function Operations

You can store up to 20 functions in memory. Functions in memory can be edited,
recalled, and graphed.
k k k k 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 Function Menu is on the display, press 3 (TYPE) to display
2. Press the function key that corresponds to the graph type you want to specify.

the graph type menu, which contains the following items.
• {Y=}/{r=}/{Parm}/{X=c} ... {rectangular coordinate}/{polar coordinate}/
{parametric}/{X=constant} graph
• {Y>}/{Y<}/{Yt t t t t }/{Ys s s s s } ... {Y>f(x)}/{Y<f(x)}/{Y>f(x)}/{Y<f(x)} inequality graph
Example To store the following expression in memory area Y1 :
y x

= 2
3(TYPE)1(Y =) (Specifies rectangular coordinate expression.)
cvx-f(Inputs expression.)
w (Stores expression.)
• You will not be able to store the expression in an area that already contains a
parametric function. Select another area to store your expression or delete the
existing parametric function first. This also applies when storing
sions, X = constant expressions, and ineqalities.
Example To store the following expression in memory area r2 :
= 5 sin 3 θ
