A lake in East Texas was stocked with 3,000 trout in the year 2000. The number of fish in the lake is modeled by f(x) = 3000 + 100x, where x represents the number of years after 2000.

Which of the following is the most reasonable domain and range for the function?

x ≥ 0, y ≥ -3000

x ≥ 0, y ≥ 0

x ≥ 0, y ≥ 3000
