3.1 - Functions and Function Notation, pg. 160, Learning Objectives * Determine whether a relation represents a function. * Find the value of a function. * Determine whether a function is one-to-one. * Use the vertical line test to identify functions. * Graph the functions listed in the library of functions. 3.2 - Domain and Range, pg. 180, Learning Objectives * Find the domain of a function defined by an equation. * Graph piecewise-defined functions. 3.3 - Rates of Change and Behavior of Graphs, pg. 196, Learning Objectives * Find the average rate of change of a function. * Use a graph to determine where a function is increasing, decreasing, or constant. * Use a graph to locate local maxima and local minima. * Use a graph to locate the absolute maximum and absolute minimum. 4.1 - Review of slopes and functions, pg. 280, Learning Objectives * Represent a linear function. * Determine whether a linear function is increasing, decreasing, or constant. * Interpret slope as a rate of change. * Write and interpret an equation for a linear function. * Graph linear functions. * Determine whether lines are parallel or perpendicular. * Write the equation of a line parallel or perpendicular to a given line.
