##### Q.02

**Solution:**

First of all, we shall find the following limits.

**(i)**

**Limit of at .**

This is because as approaches 0 from left side, approaches 1.

The reason is as approaches 0 from the right side, approaches -2.

Since

Therefore does not exist.

**(ii)**

**Limit of at**

We see from the figure given in the book that as from left side, approaches 0.

because as from the right side, approaches 0.

Since

Therefore

**(iii)**

**Limit of at**

We see from the figure given in the book that as from left side, approaches 0.

because as from the right side, approaches 0.

Since

Therefore

**(iv)**

**Limit of at**

As

(a)

(b)

(c)

(d)

(a)

(b)

limit does not exist because does not exist.
