You can put this solution on YOUR website!
In gral abs(f(x)) < k with k > 0 if only if -k < f(x) < k so\r
\n" ); document.write( "\n" ); document.write( "abs((x-1)/9) < 2 if only if -2<(x-1)/9<2 if only if -18 < x-1 < 18
\n" ); document.write( "if only if -17 < x < 19 so the solution is the interval (-17,19) \n" ); document.write( "

\n" );
