Step 2
Consider the left sided limit.
Step 3
As the values approach from the left, the function values decrease without bound.
Step 4
Consider the right sided limit.
Step 5
As the values approach from the right, the function values increase without bound.
Step 6
Since the left sided and right sided limits are not equal, the limit does not exist.
