$DNE$

Verified step by step guidance

Observe the graph of f(x) and identify the behavior of the function as x approaches 1 from both sides.

Notice that as x approaches 1 from the left (x < 1), the function f(x) is approaching the value 2.

Similarly, as x approaches 1 from the right (x > 1), the function f(x) is also approaching the value 2.

Since the function approaches the same value from both sides, the limit exists.

Conclude that the limit of f(x) as x approaches 1 is 2, because the function approaches the same value from both sides.
