or 

y = 3x 

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.

y = -2x2 + 3

Show boards

300

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
