## Kerala Plus One Maths Notes Chapter 13 Limits and Derivatives

**Limits of a function at x = a**

- When we say that x approaches a (x → a) then we mean that the variable x takes those values which are either less than ‘a’ or greater than ‘a’ and the numerical difference between ‘x’ and ‘a’ can be made as small as we please.
- Let f (x) be a function of x. Let ‘a’ and ‘l’ be constants such that as x→ a we have

f (x) → l in such a case we say that the limit of function f (x) as x approaches ‘a’ is ‘l’ - . In case no such number exists, then we say that J™
^{/w}does not exist finitely.
