document.write( "Question 206133: The section we are currently working on in class is titled \"Rational Expressions and Functions.\" The directions for the problems are to 'Find all values of the variable for which the given rational function is undefined. Then express the domain in interval notation.' Unfortunately some of the equations are more complex. How do I go about solving such a problem as this one:\r
