A function is a special relationship where each input has a single output.
In this case at any given time (input) the oven was exactly one temperature (a single output.
5:00 ------------------72º F
5:05------------------250º F
5:10------------------400ºF
5:20------------------400ºF
5:30------------------400ºF
5:45------------------400ºF
6:00------------------400ºF
6:30------------------300ºF
6:55------------------72ºF

Answer:

The correct option is:

A. It is a function because at any given time the oven was exactly one temperature.

Step-by-step explanation:

It is given that:

At 5:00 p.m., Antonio turned on the oven.

The oven remained at 400°F for 45 minutes until Antonio turned it off.

It took 60 minutes for the temperature in the oven to cool, returning to 72°F at 6:55 p.m.

The statement that best explains whether the temperature in the oven is a function of the time or not is:

A. It is a function because at any given time the oven was exactly one temperature.

( Since the definition of function states that there is a unique image corresponding to a element hence here the temperature at a given time is unique)
