The path of a football kicked by a field goal kicker can be modeled by the equation y = –0.03x2 + 1.53x, where x is the horizontal distance in yards and y is the corresponding height in yards.

What is the football’s maximum height? Round to the nearest tenth.
yds.
How far is the football kicked?
yds.

For the second part, "How far is the football kicked (yds).
Y will equal 0 two times, y at 0 means the foot ball is on the ground.  It will be on the ground at the beginning and at the end of the kick.

Soooo let y=0 and solve the quadratic, ignore the 0 answer but the other answer is what you want.

I would help on the first one, but I would be using calculus (derivatives) and I am not sure you have had this yet as this is the algebra forum.
