You can put this solution on YOUR website!
Let's put empty parentheses in these equations instead of x:
\n" ); document.write( "f( )=-3( )-3\r
\n" ); document.write( "\n" ); document.write( "g( )=( )^2+2( )
\n" ); document.write( "Then fill in the blanks with 2:
\n" ); document.write( " $\"f%282%29=-3%282%29-3\"$ $\"g%282%29=%282%29%5E2%2B2%282%29\"$
\n" ); document.write( "so f(2)=3 and g(2)=8
\n" ); document.write( "then (f-g)(2)=3-8=-5\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
