Graphing the Cosine Curve with a Period Shift

The video tutorial explains how to analyze and graph the function F(x) = 2cos(x + π). It covers finding the amplitude and period, determining critical points, and graphing the function with transformations. The tutorial also compares the transformed graph with the parent cosine function, highlighting changes in amplitude and starting points.

Describe the critical points of the cosine function and their significance.
