7-130.

Kendra just made a cup of hot chocolate that was too hot for her to drink. She set it aside so it could cool off. While she was waiting, her friend Lara called and Kendra forgot about her hot chocolate. Sketch a graph that shows the temperature of the hot chocolate since Kendra first set it aside. How cold will the hot chocolate get? Homework Help ✎

Think of the shape of the graph. Will it be linear or exponential?

Remember that the temperature of the room is not 0°.
Can the hot chocolate ever drop below the temperature of the room?
