Question 1130187: The path a tennis ball takes from a players forehand ground stroke can be modeled by the function:h(d)= 0.013(d-8)^2+1.3 . where h(d)is the height of the ball and d is the horizontal distance the ball has traveled since it was struck.
a) What is the maximum height the tennis ball reaches?
b) How far has the ball traveled horizontally from where it was struck when it reaches its
maximum height?
c) What was the height of the ball when it was struck?
d) How far did the ball travel horizontally from where it was struck to where it landed inside the court?
e) If the opponent is standing 12 meters away, at what height would she make contact with
the ball to volley it back?
f) State what represents the domain and the range in this example, then list the domain and range.

You can put this solution on YOUR website!
.
I just answered it before (under this link)
https://www.algebra.com/algebra/homework/quadratic/Quadratic_Equations.faq.question.1129995.html

and can only repeat it again:


            You INCORRECTLY presented the function in your post.


I can not  (and don't want)  to explain the solution to a person,  who does not understand his  (or her)  own question
and don't know the basics of things.
