Lesson Summary:

In this lesson, you will learn how to determine the intersection of two functions using the intersect command on your graphing calculator. By inputting your equations into Y= and finding a window where the intersection is visible on the screen, you can use the intersect feature to find the input values where the functions intersect. This method is useful in solving equations and finding solutions to real-world problems.

Lesson Description:
