Assuming you mean sqrt(x-3) rather than sqrt(x) - 3, the domain can be any subset of of x ≥ 3. The range will depend on the domain but needs to be divided in two so that it contains only one of the two roots.
Domain is greater than or equal to zero. same with range
The domain is (-infinity, infinity) The range is (-3, infinity) and the asymptote is y = -3
domain: (-infinity to infinity) range: ( -infinity to infinity)
domain: all real numbers range: {5}
The domain would be (...-2,-1,0,1,2...); the range: (12)
The domain and the range depends on the context. For example, the domain and the range can be the whole of the complex field. Or I could define the domain as {-2, 1, 5} and then the range would be {0, 3, -21}. When either one of the range and domain is defined, the other is implied.
The domain is what you choose it to be. You could, for example, choose the domain to be [3, 6.5] If the domain is the real numbers, the range is [-12.25, ∞).

In the complex field, the domain and range are both the whole of the complex field.If restricted to real numbers, the domain is x >= 4 and y can be all real numbers >= 0 or all real numbers <= 0 [or some zigzagging pattern of that set].
The domain could be the real numbers, in which case, the range would be the non-negative real numbers.
Domian is x>-6 Range is y> or equal to 0
domain: (-infinity to infinity) range: ( -infinity to infinity)
domain: all real numbers range: {5}
The domain would be (...-2,-1,0,1,2...); the range: (12)
The Domain and Range are both the set of real numbers.
