Using the vertex, it is found that the maximum height of the punt is of 27.7 feet.
The height of the punt, <u>after x seconds</u>, is given by:

It is a quadratic equation with coefficients
.
The maximum value is the value of the function at the vertex, hence:

Applying the coefficients:

The maximum height of the punt is of 27.7 feet.
