document.write( "    y = 4x - 2.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then we swap x and y\r\n" );
document.write( "\r\n" );
document.write( "    x = 4y - 2\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "and express \"y\" from here\r\n" );
document.write( "\r\n" );
document.write( "    y = .\r\n" );

\n" ); document.write( "\n" ); document.write( "The procedure described in my post is the standard to create an inverse function \r
\n" ); document.write( "\n" ); document.write( "(when it exists), and the wording mantra is standard and universal, too.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So, it is worth to MEMORIZE it to use for the future similar problems.\r
