You can put this solution on YOUR website!
f(x) = $\"x%5E3-5\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so, $\"y=x%5E3-5\"$
\n" ); document.write( " $\"y%2B5=x%5E3\"$
\n" ); document.write( " $\"%28y%2B5%29%5E%281%2F3%29=x\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "--> f(y) = $\"%28y%2B5%29%5E%281%2F3%29\"$
\n" ); document.write( "or $\"f%5E%28-1%29%28x%29+=+%28x%2B5%29%5E%281%2F3%29\"$ \r
\n" ); document.write( "
