asymptotes

[rachael724]

I posted one like this yesterday. I am confused on this one today. I did understand how the answer was gotten yesterday but this one has left me clueless. I dont know if it is the same concept of not

Which of the following functions has a graph with exactly four asymptotes?

a. f(x) = 1/(x^2 + 1)
b. g(x) = 1/(x - 1)
c. h(x) = 1/(x^2 - 1)
d. p(x) = 1/[(x^2 - 1)(x - 2)]
e. q(x) = x^3/[(x^2 - 3)(x2 - 5)]
f. r(x) = x^3/(x^2 + 1) I know this isn't the answer
g. none of these

How is this one different from yesterday's exercise? You understood that one, so start this one by finding the same information. What the vertical asymptotes for each? What is the horizontal asymptote, if any, for each?

When you reply showing how far you've gotten, please answer yesterday's question: Are you considering only horizontal asymptotes, or do slant/oblique asymptotes count as well?

Thank you.
