The graph shows the temperature between noon and midnight in one day in a certain city.
- Was it warmer at 3:00 p.m. or 9:00 p.m.?

- Did the temperature change more between 1:00 p.m. and 3:00 p.m. or between 3:00 p.m. and 5:00 p.m.?
- Does this graph show that temperature is a function of time, or time is a function of temperature?
- When the input for the function is 8, what is the output? What does that tell you about the time and temperature?
