• h(x)

• g(x)

Which statements describe the graph shown? Check all that apply.

• The function is linear.

• The function is quadratic.

• The height increases at a constant rate of change

• The ratio of height and number of weeks is constant.

• There is no relationship between height and number of weeks.

Which statement is True about the table?

• The y-intercept of the function is (15, 75).

• The rate of change is 15 calories burned per minute.

• A linear function to model the calories burned, y , as a function of the time in minutes, x , is y = 5x.

• An exponential function to model the calories burned, y , as a function of the time in minutes, x , is y = 5x.

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

• Linear

• Exponential

• Quadratic

• Not a function
