You can put this solution on YOUR website!
D) f(g(x))=f(6x+9)=|6x+9|

\n" ); document.write( "other are wrong :
\n" ); document.write( "
\n" ); document.write( "A) 6x+9, lack absolute value
\n" ); document.write( "B) -|6x+9|, a minus sign different
\n" ); document.write( "C) |-6x+9|, a minus sign inside the absolute value different
\n" ); document.write( "
\n" );
