Temperature on Day 3 Interval time (h) [0, 2] [2, 4] [4, 6] [6, 87 [8, 10] [10, 12] Average rate of 23-24 change on Interval 2-0 --0.5 (c) The temperature is decreasing in this 12-hour period. Is the average rate of change of temperature increasing or decreasing? (d) Which of the basic shapes in Figure 2 best describes the graph for Day 3? 6. On Day 4 the temperature also decreases from 24. C to 2 C between midnight and noon. But this time, the rate of change of temperature is increasing. Sketch a describes this situation. (You may find it helpful to consider the basic shapes in Figure 2.)
