Answer:
B. Any integer greater than 0
Step-by-step explanation:
The domain of a function is the complete set of possible values of the independent variable. It is the set of all possible values of t which will make the function "work", and will give a result for the Air Pressure, P(t).
Since Time(t) is a continuous function, the domain could take on any positive real number. Since, we are looking for the best description of the domain, Option B (any integer greater than 0) would be suitable.
This is because choosing any real number in Option A will accept negative values and time cannot be negative.
