The video tutorial covers the concepts of sine, reflection over the X-axis, vertical stretching, and compression. It explains how to transform functions by multiplying by negative values for reflection and by specific factors for stretching. The tutorial also discusses horizontal transformations, specifically shifting functions. The session concludes with a Q&A segment.
