Answer:
(a)x=100
(b)Maximum Height, h=53 Units
(c)x=200 Units
Explanation:
Given the equation which describes the path of the baseball

(a)Equation of the axis of symmetry
For a quadratic function of the form
, its equation of the axis of symmetry is determined by the equation:

In the function given: a=–0.005, b=1
Therefore:

Equation of the axis of symmetry, x=100
(b)Maximum height reached by the baseball
The maximum height reached by the baseball occurs at the line of symmetry.
Therefore, when x=100
Maximum Height,

=53 Units
(c)When the height =3 feet, we want to determine the value of x.
