6. DOMAIN AND RANGE (dependent independent): Parker wants to fill his 1200 gal pool with a fire hose which has a constant flow rate of 24 gal per min.

Question

Continued: What would be the appropriate domain and range for the situation?

Answer 1

The domain is time. At a flow rate of 24gal/min it will take 50 minutes to fill the pool (1200/24=50) so the domain is 0-50. A negative number does not make sense in the context of the question and at 50 minutes the pool is full so you would stop pumping

The rage is gallons of water in the pool which starts at 0( pool is empty) and ends at 1200 ( pool is full) So the range is 0-1200
