The limit is 1.

Step-by-step explanation:

In this kind of problem, we can use the left and right-hand limit method.

Basically, we need to find the limit by the left side and then by the right side. If both of them are equal the limit does exist if not the limit does not exist.

Left hand

Right hand

As we see, both limits are the same, so the limit is equal to 1.
