In words the answer is between t=0 and t=2.

In interval notation the answer is (0,2)

In inequality notation the answer is 0
Big note: You should make sure the function I use what you meant.

Step-by-step explanation:

I hope the function is h (t) = -16t^2+32t because that is how I'm going to interpret it.

So if we can find when the ball is on the ground or has hit the ground (this is when h=0) then we can find when it is in the air which is between those 2 numbers.

0=-16t^2+32t

0=-16t (t-2)

So at t=0 and t=2

So the ball is in the air between t=0 and t=2

Interval notation (0,2)

Inequality notation 0
