Here's a limit question which I can't seem to figure out how to do, if someone can explain how to do this one question, I'd greatly appreciate it, as I barely understand this:(adsbygoogle = window.adsbygoogle || []).push({});

In Excercise 9, a positive number E and the limit L of a function f at a are given. Find a number DELTA such that |f(x) -L| < E if 0 < |x-a| < DELTA

Excercise 9:

[tex]\lim_{x \rightarrow 4} 2x = 8; E = 0.1[/tex]

Thanks.
