Sharon incorrectly solved a limit problem. Her solution did not follow the proper steps for evaluating a limit. To help Sharon, one should explain the correct process for solving limits, including identifying the behavior of the function as the input approaches the given value, and using formal limit rules and properties. Sharon's answer seems unreasonable because it did not analyze the behavior of the function near the limit point. To avoid errors, Sharon should show the work for each step when solving a limit, and check that her solution matches the behavior of the function.

1. Briefly explain Sharon’s steps. Why do you think this solution is incorrect?
What would you say to Sharon to help with the problem?
From your understanding of what a limit is, does Sharon’s answer seem rea-
sonable or unreasonable? Explain.
What specific steps or strategies could Sharon use to avoid this type of error?
