The correct answer is C
Step-by-step 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
