You can put this solution on YOUR website!
f(x) = \"sqrt%282x%2B6%29\"
\n" ); document.write( ":
\n" ); document.write( "you know that 2x+6 has to be positive
\n" ); document.write( "Therefore if x < -3 the result would be a negative number inside the radical which is not allowed. the domain would be x => -3 to + infinity. (0 is allowed)
\n" ); document.write( "Interval notation [-3, oo)
\n" ); document.write( "
\n" );
