At the surface of the ocean, the water pressure is the same as the air pressure above the water, 15 pounds/square inch. As you descend below the surface of the water, the water pressure increases by 0.434 pounds per square inch for every 1 foot of descent. What is the change in the water pressure as you descend from 4 feet below the surface of the water to 32 feet below the surface of the water?
 pounds/square inch   

What is the change in the water pressure as you ascend from 26 feet below the surface of the water to 2 feet below the surface of the water?
 pounds/square inch   

Define a function j that determines the water pressure in terms of the number of feet you are below the surface of the water, n. (Don't forget that the water pressure is 15 pounds/square inch at the surface).

Use the function you defined in part (c) and identify the:
