Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I'm currently working on a proof problem and I'm just totally clueless on what I've been asked to prove.

The question is:

Define the real valued function f by f(x) = x^3 and prove that f(x) --> -8 as x --> -2. [ use the epsilon and delta definition of a limit ]

So far this is my attempt but I'm stuck where I'm trying to find epsilon. I'm not even sure my attempt is even correct Can someone help? Thanks in advance!
