This is an introductory book covering functions and graphs together with some applications. Functions are used in ordinary life applications, including economics and engineering. Although we do not face functions directly, problems that we face are most frequently solved by modeling them as a function.
This book is divided into four sections. The first section, relations, prepares the student for the concept of functions and introduces the cartesian coordinate system uhich uill be consistent throughout the remaining part of the book. The heart of the book is the second section in uhich we study the main concepts of functions. The third section goes more in depth with further operations of functions in a more arithmetic and theoretical way. The last section concentrates on visualization of functional terminology throughout the graphs and introduces a very important technique called transformation uhich ? ill be necessary in future concepts of algebra and mathematical analysis. Teachers may choose four different plans of teaching (sections 1+2, sections 2+2+3, sections 1+2+4, or sections 1+2+3+4) enabling you to use the book depending on the level of the students and the total hours allowed.
