Graphing the Secant Function with a Vertical Shift

The video tutorial explains how to graph secant functions by first graphing the cosine function as a reference. It covers finding amplitude and period, plotting key points, and applying vertical shifts. The tutorial also discusses the concept of asymptotes in secant graphs, emphasizing the importance of understanding reciprocal functions. The instructor provides step-by-step guidance and encourages practice to master the graphing process.
