#### Answer

The above analysis can be graphically represented as shown below:
Temperature and time cannot be negative, so. the graph will lie in the first quadrant.
On the graph, let y be the value of the temperature of the pie and x be the time:

#### Work Step by Step

Here, the initial temperature of a frozen pie is very cool.
Next, place the frozen pie in the oven for an hour.
During this section, the temperature of the pie will increase rapidly.
After one hour, take out the frozen pie from the oven.
At this stage, the pie is as hot as the oven. So, the temperature of the pie will reach its maximum
value and remains constant for a moment.
Finally, the temperature of the pie will decrease gradually,.
