Hey there everyone. I was looking at an epsilon-delta proof I did and realized that I wasn't exactly sure why one of my statements was true:(adsbygoogle = window.adsbygoogle || []).push({});

On the third last line, why is it fine to assume that .5 | x - 4 | < e is true? Isn't there a chance that .5 | x - 4 | may be greater than e?

Thanks in advance!

Edit: Hmm, wonder why the IMG tags don't work ...
