# Finally, we look at some applications of rational functions. This video from Math Dealers has some fun applications. We watch the whole video (it's short). The beginning reviews graphing and defining rational functions and the second part shows the applications. We interpret graphs and write about what they are telling us.

A rational function is simply the ratio of polynomials. Any function of one variable, x, is called a rational function if, it can be represented as the following rational function formula:

From here, we can simply divide out of the fraction. 2019-04-16 · For rational functions this may seem like a mess to deal with. However, there is a nice fact about rational functions that we can use here. A rational function will be zero at a particular value of \(x\) only if the numerator is zero at that \(x\) and the denominator isn’t zero at that \(x\). In other words, to determine if a rational function is ever zero all that we need to do is set the numerator equal to zero and solve. Rational function.

Math 1314 Rational Functions Rational Functions A rational function is the algebraic equivalent of a rational number. Recall that a rational number is one that can be expressed as a ratio of integers: p/q. Examples: 2/3, -23 ( = -23/1), 0.005 ( = 5/1000) Before we actually try to graph a rational function, it would be nice to remember what these things are! They're those guys like. Where you have a polynomial over another polynomial.

## Similarly, rational expressions extend the arithmetic of polynomials by allowing division by all polynomials except the zero polynomial. A central theme of this unit

### Rational Functions Group Activity Directions: Each Group is Given a Rational Function and must: Find and locate the x- and y-intercepts; Find the Domain and Range; Find and graph Horizontal Asymptote and the Vertical Asymptote; Graph the Functions; The project can be a race to see which team can complete the task first.

### A rational function will be zero at a particular value of x x only if the numerator is zero at that x x and the denominator isn’t zero at that x x. In other words, to determine if a rational function is ever zero all that we need to do is set the numerator equal to zero and solve.

Write an equation for a rational function with the given characteristics. 19. Vertical asymptotes at x=5 and x=−5 x intercepts at (2, 0) and ( 1, 0)− y intercept at (0, 4) Just as the polynomials are analogous to the integers, rational functions are analogous to the rational numbers. We will learn more about this analogy as we rewrite various rational expressions, and also think about their graphical behavior. Virtual Nerd's patent-pending tutorial system provides in-context information, hints, and links to supporting tutorials, synchronized with videos, each 3 to 7 minutes long.

This means we have to be worried about points where the denominator is zero. In this section we will focus on the algebraic aspects of rational functions.
