You are correct.
To determine domain, look for any restrictions that would make your function undefined (examples: division by zero, negative square root, etc.).
Your have no restrictions on the domain.
Now once you have determined any restrictions, then look at your function's ouput.
Since it's linear, then you have chosen the proper range.
