Unit 1: Functions - Properties and Characteristics Date: Lesson #7: Graphical Characteristics of Functions L. G.: I can describe graphical characteristics, e.g. zeros, maximum/minimum values, asymptotes, end behaviour, domain, and range, increasing/decreasing behaviour, continuity, even/odd symmetry, of these functions given the graph or equation of a function. Definitions: . Increasing and Decreasing Intervals: A function f, is on an interval if the value of f(x) increases as the value of x increases. f(x) f(x2) when x1
