BASEBALL The equation h = –0.005x2 + x + 3 describes the path of a baseball hit into the outfield, where h is the height and x is the horizontal distance the ball travels.

Question

a. What is the equation of the axis of symmetry?
b. What is the maximum height reached by the baseball?
c. An outfielder catches the ball three feet above the ground. How far has the ball traveled horizontally when the outfielder catches it?

Answer 1

the axis is x = -b/2a

max height reach when x = -b/2a

solve for x when h=3. There will be two answers: one when going up, and one when going back down.

Answer 2

A. x=100
B. 53
C. 200

Answer 3

How did you solve those 3 problems
