Hey guys, I found this question and it started bugging me:(adsbygoogle = window.adsbygoogle || []).push({});

find the _largest_ δ such that |x - 5| < δ => |1/x - 1/5| < 1/100.

This is what I did to try solve the question:

From |1/x - 1/5| < 1/100 : I got 1/x > 19/100 and so I wanted x < 100/19

plugging that back into the first inequality it gave δ = 5/19

But I don't think what I did is right because when I was trying values for x which satisfied this it gave answers which were over 1/100.

So my question is how would I solve this type question.

Any help is very much appreciated :)

Thank you in advance!
