You can put this solution on YOUR website! .
When you are given a rational function and they want you determine its domain,
then you always perform the same procedure.
You determine if the denominator has real roots.
If it has real roots, you exclude them from the set of all real numbers.
The rest is the domain.
To write your post correctly, use parentheses, in order we, the tutors (and the readers)
could identify, WHICH part is the numerator and WHICH part is the denominator.
