Homework Help: Calculus: End Behaviour Model

  1. Feb 24, 2005 #1
    For some reason I am having problems finding a power function end behaviour model for this question:

    f(x)= (2x + 1)/(x^2 - 2x + 1)

    Can someone help? Thanks.

    "End behaviour model"? That's not standard mathematical terminology is it?

    [tex]f(x)= \frac{2x+1}{(x-1)^2}[/tex]

    That has y= 0 as a horizontal asymptote which is how I would be inclined to interpret "end behaviour".

    Yeah, I haven't heard of that either.

    Does that mean:

    [tex]\lim_{x\rightarrow{\infty}}[/tex] and [tex]\lim_{x\rightarrow{-\infty}}[/tex] ?
