Question

the volume of air in a persons lungs can be modeled with a periodic function. the graph below represents the volume of air, in ml, in a persons lungs over time ( t ), measured in seconds.
what is the maximum and what does it represent in this context?
(the graph shows volume of air (in ml) on the y - axis and time (in seconds) on the x - axis. points on the graph include (0.25, 2500), (2.75, 1100), (5.25, 2500), (7.75, 1100))
answer attempt 1 out of 2
the maximum is (square) and it represents

Explanation:

Look for the highest y-value (volume) on the periodic graph, which is marked at points (0.25, 2500) and (5.25, 2500). This value corresponds to the greatest amount of air in the lungs at a given time.

Answer:

The maximum is 2500 mL and it represents the greatest volume of air in the person's lungs at any point during the breathing cycle.
