To know the height of the baseball when it is hit we have to compute h(0), as t = 0 is when the baseball is hit into the air.

So, the answer is <u>2 feet.</u>
<u />
h(x) is a parabola which can be written as
, it means that the vertex is the point (-b/2a,h(-b/2a)).
The baseball reached its maximum height after

And the maximum height of the baseball is h(4).

Hope this helps.
