Homework Help: Asymptotes of function

  1. Jan 24, 2009 #1
    if i am given a function y=f(x) for example,

    f(x)=[tex]\frac{x3/SUP]{x2/SUP]-1tex]

    and i am asked to find all asymptotes, i find

    vertical asymptotes : x=1 x=-1

    slant asymptote: y=x

    am i expected to write y=infinity as well since

    Lim
    x->inf = infinity

    or is this just understood since i do not have another horizontalasymptote

    I fixed up your LaTeX tags. I think this is what you meant.
    Everything looks fine. I wouldn't expect that you'd need to add that f(x) is unbounded for large or very negative x.

    thanks, thats exactly it, not that it really matters, more of a general question than this specific case
