Question

Give an example of a rational function that has no horizontal asymptote and a vertical asymptote at
x = 1.

Answer 1

x^2 / x - 1

Answer 2

Can you explain that to me? So I will know why that is the answer?

Answer 3

limit as x approaches infinity = infinity = no h.a
x - 1 = 0, when x = 1, and the function does not exist at x = 1

Answer 4

Huh? What do you mean it doesn't exist at x=1? When you graph it, it crosses the x-axis there, is that what that means?
