Graphing Cosine with a Reflection, Change in Amplitude, Period and Phase Shift

The video tutorial explains how to graph a cosine function with transformations, including amplitude, period, phase shift, and vertical transformation. It covers the impact of a negative sign indicating reflection over the X-axis and provides a step-by-step guide to graphing the function, considering all transformations and reflections.
