The temperature of food in a slow cooker increases at a constant rate. Then the slow cooker keeps the food at the same temperature. Next, the food is put in the refrigerator where it cools at a varying rate until it is colder than it was before it was cooked. Sketch a graph that shows the temperature of the food as a function of time.
