Question

Jada fills the bathtub before taking a bath and then allows the water to drain when she is done. The graph below models the number of gallons of water, y, in the bathtub over time, t, in minutes.

Answer 1

Jada always makes sure to start filling the bathtub with water before taking a relaxing bath. Once she is finished, she lets the water drain out of the tub. According to the graph below, it appears that she fills the tub quickly at first, and then the rate at which the water increases slows down over time. Eventually, the water starts to drain out and the amount of water in the tub decreases steadily until it is empty. It's important to be mindful of water usage and not let the tub overflow, so Jada always keeps an eye on the water level as she relaxes in her bath.
