Question

Each month, James drains 10 gallons of water from his fish tank and refills it with clean water. He uses a siphon vacuum that drains 1 gallon per minute. The function V(m) represents the volume of water, in gallons, drained from the fish tank after m minutes.
What is the domain of V(m)?

Answer 1

Since the siphon drains 1 gallon per minute and he stops after removing 10 gallons, m can range from 0 up to 10 minutes.
Domain: 0 ≤ m ≤ 10 (or [0, 10] in interval notation).
