The height, in feet, of an arrow shot from a bow in an upwards direction, is modeled by the function f(t)= -16t^2+96t+5, where t represents the time in minutes. during which interval is the arrow going up.  a. 0< t< 3b. 3< t< 6c. 5≤t≤149d. 16< t< 96

The vertex is at x = -96/(2*(-16)) = 3, so any interval ending in x=3 is an interval in which the function is increasing. The appropriate selection is
&nbsp; A. 0<t<3

_____
The given equation for ballistic motion on Earth is appropriate for units of t being seconds, not minutes.

I'm sure the answer is a
