4. Regardless of the actual value of the function \(f(x)\) at the point \(x=c\), the limit is still the predicted value of the function based on the values near \(x=c\). Using the SageMath app below, for the function given in your lab report, determine the limit of the function at \(x=c\) and the actual value of the function at \(x=c\).
