Answer 1

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. Which statement best explains whether or not the temperature in the oven is a function of the time?

A. It is a function because at any given time the oven was exactly one temperature.
B. It is a function because the oven temperature was the same at different times.
C. It is not a function because at any given time the oven was exactly one temperature.

Answer 6

Yep Exactly! So what is your x-variable, and what is your y-variable? I ask this so that we can create a hypothetical graph of the scenario in the question,

Answer 7

time would be my x and F ˚ would be my y

Answer 15

But if we look above, that is sort of how it looks like. The temperature increases, stays the same, then decreases. Now read the options and A makes sense. Try to draw pictures and it should help in these kinds of problems
