(b) Which do you think is a better way of expressing the rate of change of tuition, dollars per year or the percentage change per year? Il. Rates of Change and the Shapes of Graphs The graphs in Figure 1 show the temperatures in Springfield over a 12-hour period on two different days, starting at midnight. From the graphs we see that a warm front was mov overnight, causing the temperature to rise.

Complete the following tables by finding the average rates of change of temperature over consecutive 2-hour intervals. Read the temperature from each graph as accurately as you can.

Complete the following tables by finding the average rates of change of temperature over consecutive 2-hour intervals. Read the temperature from each graph as accurately as you can. Temperature on Day 1 Time interval (h) [0, 2 12, 4] [4, 6] 16, 8 [8, 10] [10, 12] Average rate of 11-5 = 3.0 change on interval 2-0 Temperature on Day 2 Time interval (h) [0, 2] 12, 4 [4, 6] 16, 8 [8, 10] 10, 12] Average rate of 5.5 5 = 0.25 change on interval 2-0 2. It is obvious from the graphs that the temperature increases on both days. Is the average rate of change of temperature increasing or decreasing on Day 1? On Day 2? 3.
