(Section 1.2: Graphs of Functions) 1.2.1SECTION 1.2: GRAPHS OF FUNCTIONSLEARNING OBJECTIVES• Know how to graph a function. • Recognize when a curve or an equation describes yas a function of x, and apply the Vertical Line Test (VLT) for this purpose. • Recognize when an equation describes a function explicitly or implicitly. • Use a graph to estimate a function’s domain, range, and specific function values. • Find zeros of a function, and relate them to x-intercepts of its graph. • Use a graph to determine where a function is increasing, decreasing, or constant. PART A: DISCUSSION• In Chapter 0, we graphed lines and circles in the Cartesian plane. • Iffis a function, then its graphin the usual Cartesian xy-plane is the graph of
