The owners of a recreation area filled a small pond with water in 120 minutes. The pond already had some water at the beginning. The graph shows the amount

of water (in liters) in the pond versus time (in minutes).
Find the range and the domain of the function shown.

Answer 1

The domain is
`0\leq x\leq 120`, and the range is
`300\leq y\leq 750`.

Be clear about what corresponds to one another, so you can decide
`x` and
`y`.
