$\"f%28x%29=%28x%2Aln%28x%29%29%5E2\"$
\n" ); document.write( "Over the interval [1,3], the minimum value of the function occurs at $\"x=1\"$ ,
\n" ); document.write( " $\"f%281%29=%281%2Aln%281%29%29%5E2=0\"$
\n" ); document.write( "and the maximum value occurs at $\"x=3\"$ ,
\n" ); document.write( " $\"f%283%29=%283%2Aln%283%29%29%5E2=9%2Aln%283%29%5E2\"$
\n" ); document.write( "So,
\n" ); document.write( " $\"f%281%29%2A%283-1%29%3C=int%28f%28x%29%2Cdx%2Cx=1%2C3%29%3C=9%2Aln%283%29%5E2%2A%283-1%29\"$
\n" ); document.write( " $\"0%3C=int%28f%28x%29%2Cdx%2Cx=1%2C3%29%3C=18%2Aln%283%29%5E2\"$ \n" ); document.write( "

\n" );
