Hi! I'm struggling with analysis at the moment and here's one question that I'm struggling with! COuld somebody please explain what I need to do, using a delta/epsilon definition(adsbygoogle = window.adsbygoogle || []).push({});

The question is:

Define what it means for a function f to be continuous at a point a.

(a) Prove directly from your definition that f(x) = x^3 is continuous

everywhere.

(b) Give an example of a function that is continuous except at

x = 1, where it is not continuous.

Thanks
