In your problem you have y=sqrt(3+x) -------- That 3+x cannot be negative;it must be >=0 So solve 3+x>=0 x>-3 The domain is all Real Numbers >=3 ------------------------- For the range you need to determine the Real Number values y CAN take. Since you have y=sqrt(3+x), y must be >=0 The range is All Real Numbers >=0 ============= Cheers, Stan H.
