Exploring Linear Functions and Transformations

This lesson covers linear functions and their transformations. It begins with an introduction to the parent function and its characteristics, such as the Y intercept and slope. The lesson then explains different types of transformations, including reflection, stretch, and shrink, and how they affect the graph of a linear function. Examples are provided to illustrate these transformations. The lesson concludes with instructions on how to graph linear functions using these transformations, emphasizing the importance of understanding these concepts for more complex functions.
