3. (a) A “one-sided limit” of the function \(f(x)\) near \(x=c\) is only concerned with the values of \(f(x)\) on a particular side of \(x=c\). A left-sided limit uses the behavior only on the left side and vice versa. Use the SageMath app below to predict the one-sided limits of the functions given in your lab report.

3. (b) For the limit to exist, both the left-sided and right-sided limits must agree. If they do agree, that value is the limit. For each function given in your lab report, determine if the limit exists.
