Best ResponseYou've already chosen the best response.0I see how you got that but is that all I need to answer this question?

Best ResponseYou've already chosen the best response.2i should think so. key is: with limits, we never get there, we just get closer and closer and closer... with your limits, we never get to x = 2 and if we come at x=2 from x = 1.99999 we get a different answer than if we come at it from x = 2.0000001
