\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Simple enough to exchange \"y\" and x.
\n" ); document.write( "\"-2y%5E2%2B6=x\"
\n" ); document.write( "\"-2y%5E2=x-6\"
\n" ); document.write( "\"y%5E2=%281%2F2%29%286-x%29\"
\n" ); document.write( "\"y%5E2=-%281%2F2%29%28x-6%29\"
\n" ); document.write( "\"y%5E2=%286-x%29%2F2\"
\n" ); document.write( "\"y=0%2B-+sqrt%28%286-x%29%2F2%29\" or \"f%5E-1%28x%29=0%2B-+sqrt%28%286-x%29%2F2%29\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "When you look at the requested graph, you want to take the part that is for \"y%3C=0\", because the inverse exchanged x and y.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Choose what you need from this RELATION (which includes BOTH inverse function branches).
