How to Graph the Cosine Graph with Multiple Transformations

The video tutorial explains how to graph the function F(x) = 3cos(x + 2π/3) - 2 by identifying and applying transformations such as amplitude, period, phase shift, and vertical translation. The instructor guides through calculating these transformations and demonstrates how to graph the function step-by-step, ensuring a clear understanding of each component's impact on the graph.
