URGENT. Please help!! The volume of air in the lungs during normal breathing is a sine function of time. The volume of
air in a person's lungs varies from 2.2L to 2.8L during normal breathing. Suppose a normal
breath takes 4 seconds, and that t = 0 corresponds to the minimum volume.

A. Draw a graph of V against t for 10 seconds, where V is the millilitres of air in the person's lungs.

B. Write an equation for the function.

C. Explain how the graph would change if the person breathes more rapidly.

*Please put full solutions including the graph. Thank you. If the answer is correct, I will brainlist.
