CHAPTER 1: Functions : Functions : Graphs of Functions : Basic Graphs and Symmetry : Transformations : Piecewise-Defined Functions ; Limits and Continuity in Calculus : Combining Functions : Symmetry Revisited : x=fy() : Inverses of One-to-One Functions : Difference Quotients : Limits and Derivatives in Calculus Functions are the building blocks of precalculus. In this CHAPTER , we will investigate the general theory of Functions and their graphs. We will study particular categories of Functions in Chapters 2, 3, 4, and even 9. (Section : Functions ) : Functions LEARNING OBJECTIVES Understand what relations and Functions are. Recognize when a relation is also a function. Accurately use function notation and terminology.
(Section 1.1: Functions) 1.1.4 TIP 1: Think of a function button on a basic calculator such as the x2 or button, which represent squaring and square root functions, respectively. If a function is applied to the input 5, the calculator can never imply, “The outputs are 1 and .” Example 4 (Ages of People) For a relation R, • The set of inputs is the set of all living people.
