...i you are given this, then
the domain will exclude the value of that makes denominator equal to zero, and it is

so, domain is:
{ element : }
interval: (,) U (,)
number line:

range:
if denominator equal to zero, is undefined =>
which means, or
interval: (,) U (,)
so, the range is:
{ element : }
