y=23x/x+18

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

**Damon**, Wednesday, April 16, 2008 at 6:09amI 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
