Answer 1

Step 1:

The function is .

Find .

Graph the function:

Observe the graph:

As tends to 1 from left hand side, approaches to 3.

As tends to 1 from right hand side, approaches to 2.

Since the right hand limit and left hand limit are not equal, limit does not exist.

Limit does not exist at .

Solution:

Limit does not exist at .
