A 1 a 1. Both have the same curve which is shifted along the x-axis. In general graphs of y f x and y f x are symmetrical relative to the X-axis.
Since b 1 the graph has a period of 2 π.
Y cos4x graph each function. Throughout this section we have learned about types of variations of sine and cosine functions and used that information to write equations from graphs.
