$\"y=3x%5E2\"$
\n" ); document.write( "Interchange x and y and solve for y, that's the inverse.
\n" ); document.write( " $\"x=3y%5E2\"$
\n" ); document.write( " $\"x%2F3=y%5E2\"$
\n" ); document.write( " $\"y=sqrt%28x%2F3%29\"$ and $\"y=-sqrt%28x%2F3%29\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"f%5E%28-1%29%28x%29=sqrt%28x%2F3%29\"$ and $\"f%5E%28-1%29%28x%29=-sqrt%28x%2F3%29\"$
