1. Identify Linear, Quadratic, and Exponential Functions N 0806.3.10Distinguish quadratic and exponential functions as nonlinear using a graph and/or a table of values. N 0806.3.11Distinguish between the equations of linear, quadratic, and exponential functions (e.g. function families such as y=x 2, y=2 x, and y=2x).

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

3. Quadratic Functions y = x 2 + 1 XY -2 Y = (-2) 2 + 1 Y = 5 Y = (-1) 2 + 1 Y = 2 0 Y = (0) 2 + 1 Y = 1 1 Y = (1) 2 + 1 Y = 2 2 Y = (2) 2 + 1 Y = 5 Y X

4. Exponential Functions y = 2 x XY -2 Y = 2 (-2) Y = ¼ or.25 Y = 2 (-1) Y = ½ or.5 0 Y = 2 (0) Y = 1 1 Y = 2 (1) Y = 2 2 Y = 2 (2) Y = 4 X Y
