Does the above-quoted portion mean "If I set the denominator equal to zero, I get no solution; does this mean that the domain is 'all real numbers', because the denominator never makes the rational expression undefined?"? If so, the answer is "yes". 1 Link to comment Share on other sites More sharing options...
