Exercise 20 Page 311

Calculate the rate of change between the data points.

Nonlinear, see solution.

Practice makes perfect

We want to determine whether the given table represents a linear or nonlinear function. To do this, we will calculate the rate of change between data points.

table

We can see that as x increases by 2, y decreases and then increases by a different amount each time. The rate of change is not constant, so this function is nonlinear.
