The domain can be anything you like: a single element, all real numbers, all complex numbers, etc.
yes. it is a function
It depends on the domain but, if the domain is the real numbers, so is the range.
Assuming the domain and range are both the real numbers (or rationals): Yes, it is 1 to 1 Yes, it is onto and the inverse is x = (y-3)/4
The range depends on the domain. If the domain is the complex field, the range is also the whole of the complex field. If the domain is x = 0 then the range is 4.

The graph of the function f(x) = 4, is the horizontal line to the x=axis, which passes through (0, 4). The domain of f is all real numbers, and the range is 4.
The domain of the function 1/2x is {0, 2, 4}. What is the range of the function?
The domain of the function f (x) = square root of (x - 2) plus 4 is Domain [2, ∞)
y = 4(2x) is an exponential function. Domain: (-∞, ∞) Range: (0, ∞) Horizontal asymptote: x-axis or y = 0 The graph cuts the y-axis at (0, 4)
