I believe the domain is x ≥ -7 because -7 is the smallest number that x can be to keep the value under the square root positive:
3√6(-7)+42
3√-42+42
3√0
0
If the number under the square root was negative, then its solutions wouldn't be real numbers. Therefore, x has to be equal to or greater than -7.
