It's the first one. That is a perfect square polynomial, which, when factored, will give you the same binomial twice, or multiplicity 2. It will factor to 
, where the vertex (h, k), is (-9, 0).
Chech the picture below.
if the person kicked it from the ground, that means its initial height is 0.
it reaches its maximum height at the y-coordinate of its vertex, and it will hit the ground when y = 0, as you see in the picture.
now let's find the y-coordinate of its vertex
when will it hit the ground?
