Jamie kicked a soccer ball that traveled along a path described by the parabola y = -x^2 +8x, where y equals the height of the soccer ball in feet, and x = the horizontal distance in feet that the ball has traveled from jamie.  how many feet from jamie does the soccer ball hit the ground?

Equation of any Parabola is of the form y=

If a is negative the parabola opens down.

The given equation of  soccer ball that traveled along a path was y=

Comparing the two equations we have a=-1,b=8

As a is negative the parabola opens down and will have the maximum point at  vertex .

The x of vertex is given by x=

Substituting a and b values we have:

x=

The y of vertex is y=

The highest point the soccer ball hit the ground is 16 ft.
