Question

Let r(x) = p(x)/q(x), where p & q are polynomials of degree n & m, respectively. We can express p and q as:

a/ Assume p and q have no common zeros. Where do the vertical asymptotes of r(x) occur? Explain in terms of p(x) and/or q(x).

b/ As x → −∞ (or x → ∞), what term dominates the behavior of p(x)?

c/ As x → −∞ (or x → ∞), what term dominates the behavior of q(x)?

We can express p and q as:
p(x)
Anx¹ + an_1x¹-1 +
+ ao
and
q(x) = bmxm + bm-1xm. +
+ bo
where (i). all aj, b¡ are constants, (ii). m, n ≥ 0 are constant integers, and (iii). an, bm ‡ 0.
=
