$\"f%28x%29=x%5E3%2B1\"$
\n" ); document.write( " $\"y+=+x%5E3+%2B+1\"$
\n" ); document.write( "to find the inverse, swap x and y
\n" ); document.write( " $\"x+=+y%5E3+%2B+1\"$
\n" ); document.write( "solve for y
\n" ); document.write( "y^3 = x - 1
\n" ); document.write( "Find the cube root of both sides
\n" ); document.write( "y = $\"3sqrt%28x-1%29\"$
\n" ); document.write( " $\"f%28x%5E-1%29+=+3sqrt%28x-1%29\"$ \n" ); document.write( "
