Question

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?​

Answer 1

The correct answer is C

Explanation:

I found this because the pond already has 3000 fish so y can not be less than 3000. Thus eliminating choice A since it says y>-3000.

That reasoning also eliminates answer D because real numbers can also include negatives.

Finally, since y has to be greater than 3000, answer B is not possible as it says y>0 which means it could be less than 3000.

In conclusion, Answer C is correct
