Graphing Cosine with Period Change and Phase Shift

The video tutorial explains how to graph the function F(x) = -3cos(2x + π). It covers determining the amplitude, period, and X scale, finding the start and end points for graphing, plotting points on the X axis, extending the graph in the negative direction, scaling the Y axis, and reflecting the graph. The tutorial concludes with a demonstration of graphing two periods of the function.
