While watering her outdoor plants, Maura noticed that the water coming out of her garden hose followed a parabolic path. Thinking that she might be able to model the path of the water with an equation, she quickly took some measurements. The highest point the water reached was feet, and it landed on the plants feet from where she was standing. Both the nozzle of the hose and the top of the flowers were feet above the ground. Help Maura write an equation that describes the path of the water from the hose to the top of her plants. What domain and range make sense for the model?

Refer to problem 2-69 in Lesson 2.1.5.

The domain is all the possible -values that make sense in this problem. The range is all the possible -values that make sense in the problem. For example, there won’t be any negative -values here.
