The domain is all the points where this expression makes sense. It makes sense for any value of x, so its domain is all real numbers.

Let's graph it to see its graph, that would quickly give you the idea of what it looks like

You can see that the smallest value is clearly -3, and there is no biggest value -- any number above 3. That makes its range from -3 to infinity.
