Answer 2

Answer:

Domain (-∞,∞)

Step-by-step explanation:

The domain of a function could be described as the set of values we can enter to it so we would have a real solution. In this case we can enter any number because we dont have any restriction (i.e. division by zero, negative square root), that would make it have a non real solution.

In other words $x$ can be any number and we will always have a real solution
