$\"y=3sqrt%28x-2%29\"$ solve for $\"x\"$
\n" ); document.write( " $\"y%2F3=sqrt%28x-2%29\"$
\n" ); document.write( " $\"x-2=y%5E2%2F9\"$
\n" ); document.write( " $\"x=y%5E2%2F9%2B2\"$
\n" ); document.write( " $\"x=%28y%5E2%2B18%29%2F9\"$
\n" ); document.write( " $\"f%5E-1=%28x%5E2%2B18%29%2F9\"$ \n" ); document.write( "
