Drawing a Graph
u To c r eate 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.
