You can put this solution on YOUR website!
the domain = all possible input values of x
\n" ); document.write( "-
\n" ); document.write( "Any values of x that make the function, p(x) undefined are not allowed.
\n" ); document.write( "for instance if p(x)=1/(x-3) then x=3 is not allowed because x=3 makes P(3) undefined.
\n" ); document.write( "-
\n" ); document.write( "since no values of x, makes the function. p(x) undefined, then all real values of x are allowed as the domain.
\n" ); document.write( "
\n" );
