Sec 5: Vertical Asymptotes & the Intermediate Value Theorem. If f(x) approaches ±∞ as x approaches c from the left or right, then the line x = c is a vertical asymptote . Vertical Asymptotes can be determined by finding where there is non-removable discontinuity in a rational function.

If f(x) approaches ±∞ as x approaches c from the left or right, then the line x = c is a vertical asymptote. • Vertical Asymptotes can be determined by finding where there is non-removable discontinuity in a rational function. Definition of a Vertical Asymptote
A. C. B. D. Ex 1: Determine all Vertical Asymptotes
If f is continuous on [a, b] and k is any number between f(a) and f(b), then there is a c in [a, b] such that f(c) = k. INTERMEDIATE VALUE THEOREM
Use the IVT to show that f(x) = x³ + 2x – 1 has a zero (x-intercept so y = 0) in the interval [0, 1]. Example 1
Verify that the IVT applies to the indicated interval and find the value of c that is guaranteed by the theorem. f(x) = x² - 6x + 8 on the interval [-1, 3] where f(c) = 0. Example 2
