Just adding 2 to both sides. 3x is equal to 2 thirds. So this is another interesting point that we haven't really hit upon before. That might be an inflection point. And the reason why I say it might be is because the second derivative is definitely 0 here. You put 2 thirds here, you're going to get 0. What we have to do is see whether the second derivative is positive or negative on either sides of 2 thirds.
