WebWe do not need to use the concept of limits (which is a little difficult) to find the vertical asymptotes of a rational function. Instead, use the following steps: Step 1: Simplify the rational function. i.e., Factor the numerator and denominator of the rational function and cancel the common factors. WebOct 25, 2024 · By looking at the graph of a rational function, we can investigate its local behavior and easily see whether there are asymptotes. We may even be able to approximate their location. ... Notice that, while the graph of a rational function will never cross a vertical asymptote, the graph may or may not cross a horizontal or slant …

Finding Vertical Asymptote(s) A rational function reduced to lowest terms (all factors common to both numerator and denominator cancelled out) will have a vertical asymptote at every value of x that would make the denominator equal zero. WebA horizontal asymptote (HA) of a function is an imaginary horizontal line to which its graph appears to be very close but never touch. It is of the form y = some number. Here, "some number" is closely connected to the … WebNov 18, 2015 · You did not set x = 2, which is where the vertical asymptote lies.
