In this section, you will learn how to find the hole of a rational function. And we will be able to find the hole of a function, only if it is a rational function. That is, the function has to be in the form of . f(x) = P/Q. Example : Rational Function
holes\:f(x)=\frac{5x-x^{2}}{x^{4}-25x^{2}} holes\:f(x)=20\frac{(x-3)(x+4)}{(x-3)^{2}(x-5)} holes\:f(x)=\frac{x(x-1)^{2}}{(x^{2}-1)}
👉 Learn how to find the vertical/horizontal asymptotes of a function. An asymptote is a line that the graph of a function approaches but never touches. The ...
1. How do you find the holes of a rational function? 2. What’s the difference between a hole and a removable discontinuity? 3. If you see a hollow circle on a graph, what does that mean? Without graphing, identify the location of the holes of the following functions. \(\ f(x)=\frac{x^{2}+3 x-4}{x-1}\) \(\ g(x)=\frac{x^{2}+8 x+15}{x+3}\)
Here are some helpful steps to remember when finding the holes of a rational function: Express the rational function’s numerator and denominator in factored form. Look out for common factors shared by the numerator and denominator. Equate each common factor to 0, then solve for x. Simplify the function’s expression.

Asymptotes. An asymptote is a line that a graph approaches without touching. If a graph has a horizontal asymptote of y = k, then part of the graph approaches the line y = k without touching it-- y is almost equal to k, but y is never exactly equal to k.
