A swimming pool holds 1800 gallons of water. At the end of the summer, the pool must be drained for 3 hours. While the pool is drained, the number of gallons of water left in the pool g, after t minutes of draining, is modeled by the function g = 1800 - 10t. What are the domain and range of this function? O 2,4 OA D={t|t< 180}, R = {g | g < 1800} OB D={t|t z 0}, R = {g | g > 0} OC D= {t|0si< 180}, R = {g |0
