Find the domain and write in interval notation \n" ); document.write( "f(x)= (2x+1)/(3x+5) \n" ); document.write( "------- \n" ); document.write( "Domain: The only restriction on \"x\" is that the \n" ); document.write( "denominator of the fraction must not be zero. \n" ); document.write( "3x+5 = 0 when x = -5/3 \n" ); document.write( "Therefore the domain is \"All Real Numbers except x = -5/3\". \n" ); document.write( "Interval Notation: (-inf,-5/3)U(-5/3,+inf) \n" ); document.write( "==================================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
