The graph of the exponential function y = 0.2491e0.0081x approximates the population growth in Baltimore, Maryland.
The graph of the exponential function y = 0.0023e0.0089x approximates the population growth in Hagerstown, Maryland. The trends can be used to predict what the population will be in the future in each city. In this lesson you will compare the graphs of linear, quadratic and exponential functions.
Helpful Hint Remember to find the average rate of change over a data set, find the slope between the first and last data point.
Comparing the Average Rates of Change of Two Functions George tracked the cost of gas from two separate gas stations. The table shows the cost of gas for one of the stations and the graph shows the cost of gas for the second station. Compare the average rates and explain what the difference in rate of change represents.

Comparing the Average Rates of Change of Two Functions John and Mike opened savings accounts on the same day. They did not deposit any money initially, but deposited each week as shown by the graph and the table. Compare the average rates of change and explain what the rates represent in this situation.
Comparing the Average Rates of Change of Two Functions John and Mike opened savings accounts on the same day. They did not deposit any money initially, but deposited each week as shown by the graph and the table. Compare the average rates of change and explain what the rates represent in this situation. Mike saves about 43 cents more per week.
