Determine if the graph is linear, quadratic, or exponential. Describe the rate of change.

• Linear; the rate of change is the same (constant)

• Linear; the rate of change gets bigger as x increases 

• Quadratic; the rate of change is negative then positive 

• Exponential; the rate of change is always positive
