You can put this solution on YOUR website!
To find an inverse function, first interchange the variables:
\n" ); document.write( "Instead of writing
\n" ); document.write( "\"y+=+4x%5E3+-+8\", write
\n" ); document.write( "\"x+=+4y%5E3+-+8+\", and solve for y.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "To solve for y, add +8 to each side:
\n" ); document.write( "\"x%2B8+=+4y%5E3+\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Divide both sides by 4:
\n" ); document.write( "\"%28x%2B8%29%2F4=+y%5E3\"
\n" ); document.write( "\"y%5E3+=+%28x%2B8%29%2F4\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Take the cube root of each side:
\n" ); document.write( "\"y+=+root%283%2C%28x%2B8%29%2F4%29\"\r
\n" ); document.write( "
