This video tutorial teaches how to find the intersection points of two graphs using a TI-89 calculator. It begins with an introduction to the concept of intersection points and their importance in math classes. The tutorial then demonstrates how to graph a parabola and a line, and explains different methods to solve for their intersection points, including algebraic methods and graphing. Finally, it provides a step-by-step guide on using the TI-89 calculator to accurately find these points, highlighting the importance of selecting the correct curves and setting bounds.
