You are filling a 19,400 gallon pool, w. The pool fills at a rate of 8 gallons per minute, m. The amount of water in the pool at any given minutes can be found using the equation. What is the domain and range.

Answer 1

assuming you start at time m=0, with w(0) = 0
That is, with an empty pool,

w(m) = 8m

19400gal / (8gal/min) = 2425 min
So, the domain is [0,2425]
the range is [0,19400]
