A basketball is thrown upwards. The height f(t), in feet, of the basketball at time t, in seconds, is given by the following function:

f(t) = -16t2 + 94t + 12

Which of the following is a reasonable domain of the graph of the function when the basketball falls from its maximum height to the ground?
A.3

hi Directrix do u mind helping me ?? (:

oh wait Directrix Im sorry for this question all I was needing to know is if I had gote it right, but I had picked (A). is that correct

directrix · Answer

I'm working on it now so hold on.

I got this:  A  .3 < t < 6 

The vertex is at approximately (3,150) so the domain of the fall starts at 3 and stops at the larger x intercept of 6.
