\n" ); document.write( "The denominator can't be 0
\n" ); document.write( "so 2x^2-5x-3 or (2x+1)(x-3)=0 when x=-1/2 or 3
\n" ); document.write( "(-oo, -1/2)U (-1/2, 3) U (3, oo) is domain
\n" ); document.write( "range is all reals
\n" ); document.write( "when x approaches 3 from positive side, for example, the denominator approaches a small positive.
\n" ); document.write( "from negative side, the denominator approaches a small negative
\n" ); document.write( " \n" ); document.write( "
