4. AP Calculus AB Infinite Limits Vertical Asymptotes VideoVideo Part 1

5. Infinite Limit- f(x) increases or decreases without bound. Means that while the limit FAILS TO EXIST, the function will increase without bound.

7. Vertical Asymptote The line x = a is a vertical asymptote of the graph of a function y = f(x) if either

8. THM: Anytime you get a nonzero number over zero, there is a vertical asymptote at that x value. EX/

9. BUT, a vertical asymptote DOES NOT guarantee the limit exists

14. So… Bottom degree bigger Same degree Top degree bigger limit = 0 limit = # (the ratio of coefficients) + or - infinitiy

15. End Behavior Models Same rules as Horizontal Asymptotes Algebraically: Divide by highest degree of the denominator.
