Domain is the set of x values for which the function is defined.
A function like this is defined for all x values.
A function like is defined for all x values except since division by zero is undefined.
A function like is defined for all x except when or since the square root of a negative number is not defined.
Look for the values which would cause the function to be undefined and those are the exceptions to the domain.
In this case,
Domain : (,)
