In math many times you are asked to show the value that a function approaches instead of actually solving for a function at a given point. When you are searching for where a function approaches you are looking for the limit.

You will see this written in the form: limits

Usually after this they will define what the function, f(x), is so that you can solve the problem. In this instance we are looking for the limit of f(x) as x approaches C from both sides. It's very important to know that you are looking at the limit as it approaches from both sides of C.
