1. Infinite Limits Lesson 2.5

2. Previous Mention of Discontinuity  A function can be discontinuous at a point The function goes to infinity at one or both sides of the point, known as a pole  Example Y=Enter this function into the Y= screen of your calculator Use standard zoom

3. A Special Discontinuity  Using standard-zoom ♦Y  Note results of tables (♦Y)

4. Definition of Infinite Limits  Given function f defined for all reals on open interval containing c (except possibly x = c)

5. Definition of Infinite Limits M --------------

6. Vertical Asymptotes  When f(x) approaches infinity as x → c Note some calculators draw false asymptote  Vertical asymptotes generated by rational functions when g(x) = 0 c

7. Properties of Infinite Limits  Given Then  Sum/Difference  Product  Quotient

8. Try It Out  Find vertical asymptote  Find the limit  Determine the one sided limit
