Question

Can you check my answers for Domain and Range? Thank you so much.

Problem number 1
2 SQRT(x) + 3
Domain: (x:x greater than or equal to 0)
Range: (y:y greater than or equal to 3)

Problem number 2
SQRT(2x + 6)
Domain (x:x greater than or equal to -3)
Range (y:y greater than or equal to 0)

Problem number three
SQRT(3x - 3) - 2
Domain (x:x greater than or equal to 1)
Range (y:y greater than or equal to -2)

Please be blatant if I'm wrong, I want to get good marks, and won't be hurt if they are. Any insight is much appreciated!
