A baseball is hit into the air, and its height h in feet after t seconds is given by h(t)= -16t^2+128t+2. The height of the baseball when it is hit is ? The baseball reaches its maximum height after ? The maximum height of the baseball is ?

Step-by-step explanation:

Hello,

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 2 feet.

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.

Do not hesitate if you need further explanation.
