Answer :
Domain: The set of all possible input values (commonly the "x" variable) It is the set of all real numbers for which a function is mathematically defined.
[tex]\mathrm{The\:function\:domain} \ x\ \textless \ 0 \ or \ x\ \textgreater \ 0[/tex]
The function has noun defined points nor domain constraints. Therefore,
the domain is x=0
[tex]\mathrm{The\:function\:domain} \ x\ \textless \ 0 \ or \ x\ \textgreater \ 0[/tex]
The function has noun defined points nor domain constraints. Therefore,
the domain is x=0
