Answer:
B. Does not exist
Step-by-step explanation:
In a two-sided limit (x approaches any number from both sides), we have to take into account how x approaches the number from the left and from the right. As x approaches -1 from the left, the limit is 2. But as x approaches -1 from the right, the limit is 0. These limits do not equal each other, and therefore the limit as x approaches -1 does not exist.
