Drawing a Graph
u To store an X = constant expression *
1
Example To store the following expression in memory area X4 :
X = 3
3(TYPE)4(X=c) (Specifies X = constant expression.)
d(Inputs expression.)
w(Stores expression.)
• Inputting X, Y, T, r, or
θ
for the constant in the above procedures causes an error.
u To store an inequality *
1
Example To store the following inequality in memory area Y5 :
y > x
2
– 2x – 6
3(TYPE)6(g)1(Y>) (Specifies an inequality.)
vx-cv-g(Inputs expression.)
w(Stores expression.)
u To create a composite function
Example To use relations in Y1 and Y2 to create composite functions for Y3
and Y4
Y1= (X
+
1), Y2
=
X
2
+
3
Assign Y1
°
Y2 to Y3, and Y2
°
Y1 to Y4.
(Y1

4) Y2
°
Y1 = ( (X

–1))
Input relations into Y3 and Y4.
3(TYPE)1(Y=)J4(GRPH)
1(Y)b(1(Y)c)w

(1(Y)b)w
• A composite function can consist of up to five functions.

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.
