Drawing a Graph
u
To store an X = constant expression *

Example To store the following expression in memory area X4 : X = 3

(X=c) (Specifi es 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 − 2 x − 6

(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
° Y2 = ((x
2 + 3) +1 ) = (x 2 + 4) Y2 ° Y1 = ( (X + 1)) 2 + 3 = X + 4 (X > −1))
Input relations into Y3 and Y4.

• A composite function can consist of up to fi ve functions.
* 1 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.
