$\"y=-x%5E2-8\"$
\n" ); document.write( "Interchange x and y and solve for y.
\n" ); document.write( "The new y is the inverse.
\n" ); document.write( " $\"x=-y%5E2-8\"$
\n" ); document.write( " $\"-y%5E2=x%2B8\"$
\n" ); document.write( " $\"y%5E2=-%28x%2B8%29\"$
\n" ); document.write( " $\"y=0+%2B-+sqrt%28-%28x%2B8%29%29\"$
