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, ∞).
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 could be the real numbers, in which case, the range would be the non-negative real numbers.
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].
domain is set of real numbers range is set of real numbers
The answer depends on the domain. If the domain is the whole of the real numbers, the range in y ≥ 1. However, you can choose to have the domain as [1, 2] in which case the range will be [2, 5]. If you choose another domain you will get another range.

D = {x [element of reals]}R = {y [element of reals]|y >= 4}
Y = x squared -4x plus 3 is an equation of a function. It is neither called a domain nor a range.
The answer depends on the domain for x. For example, if the domain is x = 7, then the range is 55. If the domain is all Real numbers, then the range is y >= 6.
The domain is (-infinity, infinity) The range is (-3, infinity) and the asymptote is y = -3
y is greater than 0 x exist in a set of real numbers
The domain could be the real numbers, in which case, the range would be the non-negative real numbers.
x
The domain of y = 1/x2 is all numbers from -infinity to + infinity except zero. The range is all positive numbers from zero to +infinity, except +infinity.
domain: (-infinity to infinity) range: ( -infinity to infinity)
The domain would be (...-2,-1,0,1,2...); the range: (12)
domain: all real numbers range: {5}
