Finding Intersections of Exponential Functions

The video tutorial explains how to determine the intersection of the graphs y = 2^x and y = 8. It begins with a brief introduction to exponentials and graph intersections. The instructor demonstrates an algebraic method to find the intersection point, followed by a graphical solution using a calculator. The intersection is found to be at (3, 8). The tutorial concludes with a summary of the methods used.
