Determine If Quadratic or Linear

f(x)

h(x)

g(x)

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.

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.

Neither

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
