f(x)=2x+4/3x-4
\n" ); document.write( "\"y+=+%282x%2B4%29%2F%283x-4%29\"
\n" ); document.write( "........
\n" ); document.write( "\"x+=+%282y%2B4%29%2F%283y-4%29\"
\n" ); document.write( "x(3y-4) = 2y + 4
\n" ); document.write( "3yx - 4x = 2y + 4
\n" ); document.write( "3yx - 2y = 4x+4
\n" ); document.write( "y(3x-2) = 4x + 4
\n" ); document.write( ".........
\n" ); document.write( "y = \"%284x%2B4%29%2F%283x-2%29\"
\n" ); document.write( "\"f%5E%28-1%29+=+%284x%2B4%29%2F%283x-2%29\"
