a. Find the limit. Select the correct choice below and fill in any answer boxes in your choice,
A. (Type an integer.)
B. The limit does not exist.

To find the limit as approaches 3 from the left ( ), we evaluate the behavior of the function as gets closer and closer to 3 from values less than 3. If the function approaches a specific value, we can determine that limit; if not, the limit does not exist. It’s essential to analyze the function’s values for values just below 3 to ascertain the behavior.

If you know the specific function , plug in values like 2.9, 2.99, and 2.999 to see what number is approaching as you near 3 from the left side. This will lead you to the final answer!
