Graphing the Cosine Function with a Reflection

The video tutorial covers the graphing of cosine functions, focusing on amplitude, period, reflection, and horizontal translations. It explains how to calculate the amplitude and period, and how to graph the function with reflections and translations. The tutorial also provides tips for graphing two periods of the function and highlights key points in the graphing process.
