You can put this solution on YOUR website!
f(x)=-x-4 [substitute (a-3) for the x-term and solve as much as possible
\n" ); document.write( "f(a-3)=-x-4
\n" ); document.write( "f(a-3)=-(a-3)-4
\n" ); document.write( "f(a-3)=-a+3-4[multiply through by (-1)
\n" ); document.write( "f(a-3)=-a-1
\n" ); document.write( "f(a-3)=a+1 [multiply through by (-1) \n" ); document.write( "

\n" );
