EQUATION OF VERTICAL ASYMPTOTE WORKSHEET

Describe the vertical asymptotes and holes for the graph of each rational function.

Problem 1 :

y = (x - 2)/(x + 2) (x - 2)

Problem 2 :

y = x/x(x - 1)

Problem 3 :

y = (5 - x)/(x² - 1)

Problem 4 :

y = (x² - 2)/(x + 2)

Problem 5 :

y = (x² - 4)/(x² + 4)

Problem 6 :

y = (x + 3)/(x² - 9)

Problem 7 :

y = (x² - 25)/(x – 4)

Problem 8 :

y = (x - 2) (2x + 3)/(5x + 4) (x – 3)

Problem 9 :

y = (15x² - 7x - 2)/(x² - 4)

Answer Key
