Notes 3-4

This document discusses symmetries of graphs and functions. It defines reflection symmetry, axis/line of symmetry, point/center of symmetry, and symmetry with respect to the x-axis or y-axis. It provides examples of proving symmetry of graphs like y=x^2 and y=x. It also defines even and odd functions and discusses using the graph-translation theorem to find asymptotes. The homework assigned is problems 1 through 21 on page 183.
