We know that the vertical asymptote has a straight line equation is x = a for the graph function y = f (x), if it satisfies at least one the following conditions: lim x → a − 0 f ( x) = ± ∞. or. lim x → a +
Finding Vertical Asymptotes 1 Factor the denominator of the function. To simplify the function, you need to break the denominator into its factors as much as possible. For the purpose of finding asymptotes
