    I see no = sign in your function, functions are equations.

    I see no brackets, but I will assume you mean

    f(x) = (3x-1)/(x^2 - 10x + 26)

    solving for x^2-10x+26=0 gives no real roots, so there are no vertical asymptotes
    if f(x) = 0, then x=1/3
    so the x-intercept is 1/3
    as x ---> ∞ , f(x) ---> 0
    so y=0 or the x-axis is a horizontal asymptote
    (from above for positive x's , from below for negative x/s
    there is no slant asymptote

    I don't know what you mean by "poles"

    Here are two graphs of your function by Wolfram

    odd to be using the term "pole" which is usually reserved for functions of a complex variable. Here it is apparently used to indicate a vertical asymptote, since for a complex function

    f(z), a pole at z=c means

    lim f(z) = ∞
