Question

A submarine is 525 meters below the surface of the ocean. It is ascending at a rate of 35meters every minute. Let y be the submarine's altitude with sea level being at 0 meters. Is it discrete or continuous? And what are the domain and range?

Answer 1

y is the submarine's altitude with sea level being at 0 meters

The ascending rate = 35 meters per minute

y = 35 x , where x is the time

Given the submarine is 525 meters below the surface of water

if y = 525

x = y/35 = 525/35 = 15 minu
