Limits The concept of limit is the underpinning of calculus. In Section , we said that a function f is continuous at x = c if the values of f (x) approach f (c) as x approaches c. In this section, we define a limit, which makes precise what we mean by approaching. The Idea of a Limit We first introduce some notation: How should we find L, or even know whether such a number exists? We will look for trends in the values of f (x) as x gets closer to c, but x ≠ c.
