To find domains, denominators must not be 0 and square roots may not
be taken of negative numbers.

So denominator 
               

And what's under the square root 
                                 

-------------●=================○============>
-3 -2 -1  0  1  2  3  4  5  6  7  8  9 10 11 

Domain = [1,7)U(7,∞)
