Answer:

(-∞, ∞)

Step-by-step explanation:

To find the domain, we find how far along the x axis the line goes.

Specifically, we're looking for when x doesn't exist, because that's much easier.

So we're looking for when x is undefined. In order to have something undefined, you need the [tex]\sqrt{-something}[/tex], or [tex]\frac{anything}{0}[/tex].

As we can see, there's no part where x is undefined. Therefore, the domain is

(-∞, ∞)
