Graphing Cosine with a Vertical Translation and a Reflection

The video tutorial explains how to graph a cosine function with a reflection and vertical shift. It covers the concepts of amplitude and period, identifies key points on the graph, and demonstrates the process of reflecting and shifting the graph. The tutorial also provides clarifications on common mistakes and emphasizes the importance of performing reflections before translations.

How do you calculate the four equal parts of the period?
