The video tutorial covers the concept of inverse functions and their importance in mathematics. It begins with an introduction to inverses and logarithms, followed by an explanation of undoing equations. An exercise is provided to help understand the concept of undoing equations. The tutorial then delves into inverse functions, explaining how to verify if two functions are inverses and how to find inverse functions algebraically. The lesson concludes with a summary of key takeaways.
