First homework will be announced later this week http://edugen.wileyplus.com/edugen/class/cls416856/ Lecture 1: FUNCTIONS Common methods for representing functions are: 1. Numerically by tables 2. Geometrically by graphs 3. Algebraically by formulas Examples: b) a) y=x2 ! ! INDEPENDENT AND DEPENDENT VARIABLES For a given input x, the output of a function f is called the value of f at x or the image of x under f. Sometimes we will want to denote the output by a single letter, say y, and write y=f(x) x is called the independent variable (or argument) of f y is called the dependent variable of f For now we will only consider functions in which the independent and dependent variables are real numbers, in which case we say that f is a real-valued function of a real variable. Example 2 The equation ! ! ! has the form in which the function f is given by the formula ! ! ! For each input x, the corresponding output y is obtained by substituting x in this formula. For example, ! ! ! ! GRAPHS OF FUNCTIONS graph of f in the xy-plane is defined to be the graph of the equation y=f(x), i.e. plot points (x, f(x)) Note: No points with x<0 ! ! THE ABSOLUTE VALUE FUNCTION set of all allowable inputs (x-values) is called the domain of f ! set of outputs (y-values) that result when x varies over the domain is called the range of f Example: V=(30-2x)(16-2x)x 1.1.5 DEFINITION. If a real-valued function of a real variable is defined by a formula, and if no domain is stated explicitly, then it is to be understood that the domain consists of all real numbers for which the formula yields a real value. This is called the natural domain of the function. ! 1.3 NEW FUNCTIONS FROM OLD Example: ! ! COMPOSITION OF FUNCTIONS Example: ! ! COMPOSITION OF FUNCTIONS g o f, the composition of f and g SYMMETRY
