The practical domain of time is t ∈ [0, 4.25s].

The set of values that make feel in a particular context is referred to as the sensible area.
All feasible solutions are addressed by way of theoretical domains and stages.
domain names and stages restrict the solution sets such that they may be realistic in the parameters given
.The ball begins its motion at time t = 0s.
To locate the time while the ball hits the floor,
we solve the equation:
h(t) = -16t² + 68t
h(t) = 0
-16t² + 68t = 0
t(-16t + 68) = 0
t = 0 and -16t + 68 = 0.
16t = 68
t = 68/16
t = 4.25
h(t) is non-negative within the interval [0, 4.25].
Hence, the practical domain is 0 ≤ t ≤ 4.25 s.
