Using the vertex form, the equation of the parabola is given by:

The equation of a <em>parabola</em>, with vertex (h,k), is given by:

In which a is the leading coefficient.
In this problem, it reaches a maximum height of 10 feet after a horizontal distance of 4 feet, hence, the vertex is (4,10), that is,
. Then, the equation for the parabola is:
