Ответ:
Option A
Step-by-step explanation:
If the number is under the square root, then it is a domain, not a range
if the number is outside of the square root, then it is a range
-4 is included in A because it is a -5, if it were a positive, then it wouldn't work
because there are no negatives included in a positive.
Hope this helps!!!
