Given information
Place a frozen pie in an oven and bake it for an hour. Then take it out and let it cool before eating it.
Step-by-step explanation
Step 1.
Consider the time in the -axis and the temperature in the -axis.
At initial time when the pie is placed in an oven, the temperature of the pie increases and reaches at the oven temperature.
After it is taken out and cooled, the temperature of the pie decreases to room temperature.
Now simply use the graphing utility to sketch the rough graph of the temperature of the pie as a function of time is shown below:
From the figure, can observe that the temperature is steadily increasing at the beginning, remains constant in the middle, then decreases, and stays constant at the end.
