there are no restrictions: Domain: (-inf,inf)
OpenStudy (anonymous):
The domain (unless otherwise stated) is the maximum set of all x for which your function is defined. Here, it's defined for all real x (there are no x-values for which this function is undefined). Your domain is therefore the real line.
