The domain of this function is: RR

Explanation:

To find the domain of a function you have to check if there are any values, of variable x for which the formula has no value. Such points can be:

  1. Values for which denominator is zero,

  2. Values for which expression under a square root sign is negative,

  3. Values for which expression under log sign is less than zero.

This formula does not contain any limitations like those above, so all values of x are possible. The domain is the whole real numbers set RR.
