Consider the following exercises: 1. What are the advantages of computing limit algebraically over using tables of values or graphs? 2. Give an example of a polynomial or rational function and describe an algebraic method for finding limits for the polynomial or rational function. 3. When trying to compute lim f ( 1) by computing f (a ) , what should you do if the result is a fraction with denominator zero? 4. Write a description of the three methods for computing lim f ( ac ) Explain when each method would be used and include examples
