vertical asymptote?

Question

What is the vertical asymptote of the curve

y=(-1x^3)/x-10

Answer 1

The asymptote occurs at x=10, because the denominator then equals zero, which causes y(x) to blow up to infinity.

Answer 2

If your function is y = (-x^3)/(x - 10), then Not Eddie is correct.

But if your function is (-x^3)/x - 10, then the function does not have 0 in the domain, and since x is never 0, you can simplify the function to y = -x^2 - 10, which has no vertical asymptotes.
