A fireboat in the harbor is helping put out a fire in a warehouse on the pier. The distance from the barrel (end)
of the water cannon to the roof of the warehouse
is 120 feet, and the water shoots up 50 feet above the
barrel of the water cannon.
Sketch a graph and find an equation of the parabola that
models the path of the water from the fireboat to the fire.
Give the domain and range for which the function makes
sense in relation to the fireboat.
