Drawing a Graph
u To create a composite function
Example To register the following functions as a composite function:
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))

• A composite function can consist of up to five functions.
u To assign values to the coefficients and variables of a graph function
After you combine functions or equations into a composite function, you can assign values to
the coefficients and variables of the expression and draw a graph.
Example Assign the values –1, 0, and 1 to the expression Y = AX
2
–1, which is in
memory area A

(av(A)!.(=)-b)w
4(GRPH)b(Yn)b
(av(A)!.(=)a)w
4(GRPH)b(Yn)b
(av(A)!.(=)b)w
