Question

How do you find all the asymptotes for function `f(x) = (3 - x) / x^2`?

Answer 1

Vertical asymptote: x = 0. When x -> 0, y -> +infinity

Horizontal asymptote y = 0. When x -> -infinity y --> 0 (from + values)
When x -> +infinity, y --> 0 (from - values)

graph{(3 - x)/x^2 [-10, 10, -5, 5]}
