\"y=x%5E2-6x\"
\n" ); document.write( "\"y=x%5E2-6x%2B9-9\"
\n" ); document.write( "\"y=%28x-3%29%5E2-9\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28y-3%29%5E2-9=x\"
\n" ); document.write( "\"%28y-3%29%5E2=x%2B9\"
\n" ); document.write( "\"y-3=0%2B-+sqrt%28x%2B9%29\"
\n" ); document.write( "\"y=3%2B-+sqrt%28x%2B9%29\"
\n" ); document.write( "Here you want y less than or equal to 3, and x must be greater or equal to 0.
\n" ); document.write( "Pick \"f%5E%28-1%29%28x%29=3-sqrt%28x%2B9%29\".
