Unformatted text preview: f ( x ) is zero. So the vertical asymptotes are x =-4 and x = 5 . To ﬁnd 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 insigniﬁcant. So f ( x ) =-2 x 3 + 18 x 2-22 x-42 x 3-6 x 2-15 x + 100 behaves like-2 x 3 x 3 =-2 . So the function has a horizontal asymptote y =-2 ....
