    domain is all real numbers, there's no value that X cannot be.

    however if it was f(x) = 1/x for example, x could not be zero and thus the domain would be (-infinity, 0) (0, infinity)

    if you substitute in any value for X in your function, it will still work. therefore all reals or (-infinity, infinity) would work for the domain.
