The document discusses reflections of functions across the x-axis and y-axis. Reflecting across the y-axis causes the x-values to become opposite, resulting in the function y=f(-x). Reflecting across the x-axis causes the y-values to become opposite, resulting in the function y=-f(x). The document provides examples of determining the reflected point for a given point on a function, and instructs the reader to sketch both the original and reflected graphs.
