The domain of f is the range of its inverse.
\n" ); document.write( "The range of f is the domain of its inverse.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The vertex of f and the sign of leading coefficient tells you something about range for f.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The quick way to find the inverse of f is to switch function and x roles:
\n" ); document.write( "\"x=-3y%5E2%2B5\"
\n" ); document.write( "\"-3y%5E2=x-5\"
\n" ); document.write( "\"y%5E2=%28x-5%29%2F%28-3%29\"
\n" ); document.write( "\"y%5E2=-%28x-5%29%2F3\"
\n" ); document.write( "\"y=0%2B-+sqrt%28-%28x-5%29%2F3%29\", the inverse of f.
\n" ); document.write( "Each branch is a separate function; when both branches are put together, that is not a function.\r
