Math 1113 Objectives OpenStax Algebra & Trigonometry CHAPTER 3: FUNCTIONS Section 3.1: Functions and Function Notation Determine whether a relation represents a function. Use the Vertical Line Test to determine whether a given graph is that of a function. Find the value of a function. Determine whether a function is one-to-one. Use the Horizontal Line Test to determine whether a given graph is that of a 1-1 function. Identify and sketch the “Basic Toolkit Functions” (constant, identity, absolute value, quadratic, cubic, reciprocal, reciprocal squared, square root, and cube root). Page 175: Online Resources Page 176: Section Exercises Section 3.2: Domain and Range Find the domain of a function defined by an equation. Use interval notation and set-builder notation Find the domain and range when given a graph. Give the domain and range of the basic toolkit functions. Graph piecewise-defined functions.

Find the average rate of change of a function over an interval: Use a graph to locate local/relative extrema (maxima and minima in a neighborhood ). Use a graph to locate global/absolute extrema (maxima and minima overall ).

Create a new function by composition of functions: (f ◦ g)(x) = f (g(x)). Evaluate composite functions. Find the domain of a composite function. Decompose a composite function into component functions.

Graph functions using reflections about the x-axis or y-axis. Determine whether a function is even, odd, or neither from its graph. Graph functions using vertical and horizontal stretching and compressing. Combine transformations.
