Introduction to Inverse Functions

The video tutorial begins by revisiting the concept of functions and their inverses, a topic familiar from GCSE. It explains that an inverse function reverses the process of the original function, such as dividing by 2 instead of multiplying by 2. The tutorial introduces two methods for solving inverse functions: the function machine method and changing the subject of the formula. The function machine method involves reversing operations to find the input from the output, while the changing the subject method involves algebraic manipulation to isolate the variable. Both methods are demonstrated with examples, showing their effectiveness in solving inverse functions.
