Is that a typo or did you mean to write,
\n" ); document.write( " $\"f%5E2=x%5E2%2B2\"$ ?
\n" ); document.write( "If so,
\n" ); document.write( " $\"f%28x%29=sqrt%28x%5E2%2B2%29\"$
\n" ); document.write( " $\"f%286%29=sqrt%286%5E2%2B2%29\"$
\n" ); document.write( " $\"f%286%29=sqrt%2838%29\"$ or $\"f%286%29=-sqrt%2838%29\"$
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "If it was a typo,
\n" ); document.write( " $\"f%28x%29=x%5E2%2B2\"$
\n" ); document.write( " $\"f%286%29=6%5E2%2B2\"$
