How do you find the domain of a function when the number is outside of the paranthesese. Example would be

y=(square root of x)+3. I know that to find the domain when the number is under the square root, you have to make the number greater than or equal to zero and then add or subtract accordingly. Example would be y=(square root of x + 2), the domain would be -2.
