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. 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).
