Question

Kyla has a just finished drinking a glass of chocolate milk. She has been told that she needs to rinse the glass out before putting it in the dishwasher. She fills the glass with water, empties the water, fills the glass again with water, and then once again empties it. She then puts the glass in the dishwasher. Which of the following is a graph representing the height of the water in the glass.

Answer 1

First, the glass was empty, therefore the y-intercept of the graph is at y=0. Then, Kyla fills the glass with water and immediately empties it, and repeats the same process, therefore the graph has two zones that show the same behavior and it has no constant behavior at any time.

The graph that best represents the height of the water in the glass vs time is the third option.
