```					Identify Linear, Quadratic, and
Exponential Functions
N 0806.3.10       Distinguish quadratic and exponential
functions as nonlinear using a graph and/or a table of values.

N 0806.3.11         Distinguish between the equations of
linear, quadratic, and exponential functions (e.g. function
families such as y=x2, y=2x, and y=2x).
Linear Functions               Y

Is this function linear?
y=x+2
X                Y
Y = (-2) + 2
-2             Y=0              X
Y = (-1) + 2
-1             Y =1
Y = (0) + 2
0             Y=2
Y = (1) + 2
1             Y=3
Y = (2) + 2
2             Y=4

y = x2 + 1

X             Y
Y = (-2)2 + 1
-2          Y=5
Y = (-1)2 + 1       X
-1          Y=2
Y = (0)2 + 1
0           Y=1
Y = (1)2 + 1
1           Y=2
Y = (2)2 + 1
2           Y=5
Exponential Functions
Y

y = 2x

X        Y
Y = 2(-2)
-2   Y = ¼ or .25
X
Y=  2(-1)
-1   Y = ½ or .5
Y = 2(0)
0       Y=1
Y = 2(1)
1       Y=2
Y = 2(2)
2       Y=4
