This document discusses transformations of functions including stretches, compressions, reflections, and inverses. It defines what makes a function even or odd both graphically and symbolically. A function is even if its graph is symmetrical about the y-axis, and symbolically if f(-x) = f(x). A function is odd if its graph is symmetrical about the origin, and symbolically if f(-x) = -f(x). Examples are given of even and odd functions based on these definitions.
