This document provides examples of analyzing and graphing various functions based on their derivatives. It examines six examples: a radical function, polynomial function, trigonometric function. For each, it identifies the first and second derivatives, domain, x-intercepts, y-intercepts, asymptotes, critical numbers, possible points of inflection, and symmetry. It then analyzes the characteristics of each function graph based on the values and signs of the function, first derivative and second derivative over intervals of the domain.
