Learning to Graph Cosine with Multiple Transformations

The video tutorial explains how to graph the cosine function y = 4cos(X + π/4) + 4. It covers key concepts such as amplitude, period, vertical transformation, and phase shift. The instructor emphasizes the importance of understanding these elements to accurately graph the function. The tutorial includes step-by-step instructions for calculating the phase shift and plotting the graph, ensuring students can apply these techniques to similar problems.

Describe the process of finding the X scale for the cosine function.

What is the maximum and minimum value of the graph based on the amplitude?

How does the phase shift affect the starting point of the cosine graph?
