You can put this solution on YOUR website!
For any real number \"x\", you can get an \"F%28x%29\" .
\n" ); document.write( "In other words, the domain of \"F%28x%29\" is all the real numbers, with no restriction.
\n" ); document.write( "\"G%28F%28x%29%29=sqrt%283-x%29\" only exists when \"3-x%3E0\"<--->\"3%3E=x\" ,
\n" ); document.write( "so the domain of \"G%28F%28x%29%29\" is
\n" ); document.write( "all real numbers \"x\" such that \"x%3C=3\" (x is less than or equal to 3).
\n" ); document.write( "
\n" );
