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

• A composite function can consist of up to five 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.
