Answer:
Limit does not exist.
Step-by-step explanation:
To calculate left hand limit, we use a value slightly lesser than that of 0.
To calculate right hand limit, we use a value slightly greater than that of 0.
Let h be a very small value.
Left hand limit will be calculate at 0-h
Right hand limit will be calculate at 0+h
First of all, let us have a look at the value of f(0-h) and f(0+h)
Now, left hand limit:
=
Using equation (1):
= -1
Now, Right hand limit:
=
Using equation (2):
= 1
Since Left Hand Limit Right Hand Limit
So, the answer is:
Limit does not exist.
