Interchange the places of x and y: $\"x+=+-3y%5E3+%2B+1\"$ ,\r
\n" ); document.write( "\n" ); document.write( " $\"x+-+1+=+-3y%5E3\"$ ,
\n" ); document.write( " $\"%28x+-+1%29%2F-3+=+y%5E3\"$ ,
\n" ); document.write( " $\"root%283%2C%28x+-+1%29%2F-3%29+=+y\"$ , or
\n" ); document.write( " $\"root%283%2C%281+-+x%29%2F3%29+=+y\"$ . This is the inverse function. \n" ); document.write( "

\n" );
