A tuning fork vibrates with a frequency of 440 hertz (cycles/second). When the tuning fork is struck, it produces a change in the normal air pressure in the room. Function p represents this situation, where p(t) is the change in pressure, in pascals, relative to the normal air pressure in the room as a function of time, t, in seconds, after the tuning fork is struck.
What is the domain within the context of this situation?
The domain of the function is: t ≥
