At 5:00p.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 pm. Which statement best explains whether or not the temperature
in the oven is a function of the time?
