think back to your algebra I.
Where is the vertex of a parabola?
remember x = -b/2a ?
A player throws a ball up and toward a wall that is 17 feet high. The height h in feet of the ball after t seconds after it leaves the player's hand is modeled by h=-16t^2+25t+6. If the ball makes it to where the wall is, will it go over the wall or hit the wall?
Find the vertex as well.
