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.
