300
Function or not?
(-2, 0) (-1, 0) (0, 0) (1, 0) (2, 0)
Function, none of the inputs (x values) repeat.
300
Linear or nonlinear? Why?
Nonlinear because there isn't a constant rate of change.

Write the equation
y = 1/2x + 2
400
Function or not? 
Function.
400
Linear or nonlinear? Why?
Linear, constant rate of change.
x change is + 3
y change is + 2
