7.4 Limit of a function as $x \to \infty $ :
- Neighbourhood of $a$ is represented as $nbd(a)$.
- Let $a$ be a real number and $\delta $ be a very small positive real number, then the interval (a-$\delta $, a+$\delta $) is called the $nbd(a)$ or $N(a)$.
- If point $a$ is excluded from the interval it is called deleted neighbourhood of $a$.
