Definition of continuity :
\A function
is continuous at
, if
then it should satisfy three conditions :
(1)
is defined.
(2)
exists.
(3)
.
Check the continuity of the function at
.
Condition (1):
is defined.
If
then the function is
.

.
Condition (2):
exists.
Left hand limit :
\
Right hand limit :
\
Left hand limit and right hand limit are not equal, limit does not exist.
\
does not exist.
The limit does not exist at
.
Therefore the function
is discontinuous at
.
and
.
.
Therefore the function
is continuous at
from left side.
