Option A
It is a function because at any given time the oven was exactly one temperature.
Solution:
Given that,
At 5:00 p.m., Antonio turned on the oven
While the oven preheated, the temperature in the oven increased from 72°F to 400°F over a 10-minute period
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
From above information,
5:00 ------------ 72°F
5:10 ------------------ 400°F
5:45 ------------------ 400ºF
6:55 -------------------- 72°F
Thus at any given time (input) the oven was exactly one temperature (a single output )
Therefore the statement that best explains is:
Option 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
