30 A level Mathematics Inverse Functions Part 3

In this A-level mathematics video, we delve into finding the inverse of a function using algebraic methods. Christina walks through the essential steps, starting with setting y equal to f(x). The core of the process involves rearranging the equation to isolate x as the subject. Finally, the resulting expression is rewritten in function notation to represent the inverse. The video also clarifies how the domain of the inverse function relates to the range of the original function. This tutorial provides a clear, step-by-step algebraic approach to determine the inverse of a function, ensuring a solid understanding of the transformation. We will walk through an example to illustrate each stage of the process. Subscribe to @AxiomTutoringCourses for more A-level mathematics tutorials.
