# Temperature readings T (in °F) were recorded every two hours from midnight to 2:00 PM in Atlanta on June 4, 2013. The time t was measured in hours from midnight. t 0 2 4 6 8 10 12 14 T 74 69 68 66 70 78 82 86 (a) Use the readings to sketch a rough graph of T as a function of t.(b) Use your graph to estimate the temperature at 9:00 AM.

(a)

To determine

To sketch: A rough graph of temperature readings, T (in °F) as a function of time, t in hours from midnight.

Explanation

Take the time in hours from midnight to 2:00 PM in the x-axis and the corresponding temperatures in Fahrenheit in the y-axis. Plot the points (0, 74), (2, 69), (4, 68), (6, 66), (8, 70), (10, 78), (12, 82), and (14, 86), and obtain the graph of T. The required graph is shown below in Figure 1...

(b)

To determine

To estimate: The temperature at 9:00 am, according to the graph.
