Definition Similarly, we define a rational function as a function of the form: R(x) = p(x) q(x) R ( x) = p ( x) q ( x) where p(x) p ( x) and q(x) q ( x) are polynomial functions and q(x) q ( x) is not zero. The domain of a rational function is all real numbers except for those values that would cause division by zero. A function that is the ratio of two polynomials. It is "Rational" because one is divided by the other, like a ratio. (Note: the polynomial we divide by cannot be zero.) See: Polynomial.

In other words, R (x) is a Carlisle Area School District » Staff Directory » Math with Mrs. Wolfe » Pre-Calculus » Lesson Resources » Unit 2: Polynomial & Rational Functions Unit 2: Polynomial & Rational Functions Concept: To graph a rational function, you find the asymptotes and the intercepts, plot a few points, and then sketch in the graph. Once you get the swing of things, rational functions are actually fairly simple to graph. Let's work through a few examples.

Search for: Graph rational functions. In Example 9, we see that the numerator of a rational function reveals the x-intercepts of the graph, whereas the denominator reveals the vertical asymptotes of the graph. As with polynomials, Dynamics of a rational function The image below shows preimages of the upper and lower half-planes under several iterates of the rational function Thinking of the extended complex plane as two equilateral triangles glued together along their boundaries, with the real axis being the "seam", the preimage of the real axis effects, combinatorially, the barycentric subdivision of each face.

Plus, get practice tests, quizzes, and personalized coaching to help you succeed. Chapter 5 : Polynomial Functions. In this chapter we are going to take a more in depth look at polynomials. We’ve already solved and graphed second degree polynomials (i.e. quadratic equations/functions) and we now want to extend things out to more general polynomials. Finally, we look at some applications of rational functions.

Just as the polynomials are analogous to the integers, rational functions are analogous to the rational numbers.
