The maximum height of the football is 15.21 yards.
<h3 /><h3>Maximum height of parabola</h3>The maximum height is the vertex of the parabola, when the parabola faces down.
Given
The path of a football kicked by a field goal kicker can be modeled by the equation y = -0.04x^2 + 1.56x.
Where x is the horizontal distance in yards and y is the corresponding height in yards.
The x- coordinate of the vertex is given by;
The value of b is 1.56, and a is -0.04.
Substitute all the values in the equation
Substitute the value of x in the given equation
Hence, the maximum height of the football is 15.21 yards.
