I think it's 10...

Well, at first glance i would think that it approches zero because of the reasons you gave. That is not true though. A somewhat good check to do is plug in some values for x that get smaller and smaller and see what number it looks like it's getting close to... I've forgotten how to get a for-sure answer. But the answer to your problem is 10.


But I soo stupidly voted 0 on my first guess, but, well... whatever
