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))

• 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
