Introduction to Polynomial and Rational FunctionsDigital photography has dramatically changed the nature of photography. No longer is an image etched in the emulsionon a roll of film. Instead, nearly every aspect of recording and manipulating images is now governed by mathematics. Animage becomes a series of numbers, representing the characteristics of light striking an image sensor. When we openan image file, software on a camera or computer interprets the numbers and converts them to a visual image. Photoediting software uses complex polynomials to transform images, allowing us to manipulate the image in order to cropdetails, change the color palette, and add special effects. Inverse functions make it possible to convert from one fileformat to another. In this chapter, we will learn about these concepts and discover how mathematics can be used insuch applications.
