What is the horizontal asymptote of :

y=23x/x+18

k so i know that the horizontal asymptote is -18 so that the denominator will equal zero.

  • Calculus -

    I assume you mean:
    y = 23 x / (x+18)
    indeed the denominator goes to zero at x = 18 so you get undefined vertical asymptote at x = -18
    as x gets very large positive, this looks like 23 x/x ---> 23
    as x gets very large negative it looks like
    23 (-x/-x) ---> 23
