Unformatted text preview: f ( x ) is zero. So the vertical asymptotes are x =4 and x = 5 . To nd the horizontal asymptotes, determine the end behviour of f ( x ). As x or x  , the highest powers of x dominate, and the other terms are insignicant. So f ( x ) =2 x 3 + 18 x 222 x42 x 36 x 215 x + 100 behaves like2 x 3 x 3 =2 . So the function has a horizontal asymptote y =2 ....
