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 8 feet, and it landed on the plants
There are several ways to write the equation. It depends on how you decide to draw the x- and y-axes.
The y-axis could go through the point where the water leaves the hose at
Use the general equation of a parabola in graphing form:
After you've filled in the values for h and k, you will need to substitute one point (x, y) in order to solve for a. Then you will be able to write the equation.
