Learn How to Graph a Piecewise Function With Two Different Functions

The video tutorial covers graphing the cosine function for X values less than zero and the exponential function E to the X for X values greater than zero. The instructor explains the process of graphing these functions, highlighting key points such as the behavior of the cosine function crossing at one and the concept of open circles in graphing E to the X. The lesson emphasizes understanding the graphing process and prepares students for further learning and practice throughout the year.
