The domain and range of the equation y = 2x+8 are both [-infinity,+infinity].
Domain : set of all reals Range: set of all reals
The domain of x^3 - 2x is whatever you choose it to be. That will then determine the range.
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 domain and range of the equation y = 2x+8 are both [-infinity,+infinity].
The range depends on the domain and conversely.
Domain : set of all reals Range: set of all reals
The Range is all the Real numbers you can think of. The Domain is also all Reals.
The domain of x^3 - 2x is whatever you choose it to be. That will then determine the range.
The domain of the function 1/2x is {0, 2, 4}. What is the range of the function?
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.

That depends on whether or not 2x is a plus or a minus
2 plus 1-x divided by.
Domain and range are not sufficient to determine the y intercept. For example, the domain and range for the straight line y = 2x + 3 are the whole of the real numbers. That tells you nothing about the intercept.
