The limit expression is
.
Graph:
\Graph the function
.

Observe the graph:
\As
approaches to
from left hand side, the function
approaches to
.
As
approaches to
from right hand side, the function
approaches to
.
Since the left hand limit and the right hand limit are not equal, limit does not exist.
\Limit does not exist due to abrupt change from
to
.
No; Abrupt change. \ \
