## SN Dey Class 11 Limits Very Short Answer Type Questions Solutions

SN Dey class 11 Limits very short answer type questions Ex 1 solutions:

**Ex 1:** Give the definition of limit of a function.

**Solution:** Let $f(x)$ be a function of $x$. We say $\lim\limits_{x \to a}f(x)=L$ if the following is satisfied.

$\lim\limits_{x \to a-}f(x)=\lim\limits_{x \to a+}f(x)=L$.

In other words, both the left-hand limit and right-hand limit of $f(x)$ as $x$ tends to $a$ is equal to $L$, then we have$\lim\limits_{x \to a}f(x)=L$.

**Ex 2: **Distinguish between $\lim\limits_{x \to a} f(x)$ and $f(a)$.

**Solution:**

(i) $\lim\limits_{x \to a} f(x)$ denotes the limiting value of $f(x)$ when $x$ tends to $a$, whereas $f(a)$ is the functional value of $f(x)$ at the point $x=a$.

(ii) It may happen that $\lim\limits_{x \to a} f(x) \neq f(a)$, but if the function $f(x)$ is continous at $x=a$, then they must be equal.
