Inverse functionsmc-TY- Inverse -2009-1An Inverse function is a second function which undoes the work of the first one. In this unitwe describe two methods for finding Inverse functions , and wealso explain that the domain of afunction may need to be restricted before an Inverse function can order to master the techniques explained here it is vital that you undertake plenty of practiceexercises so that they become second reading this text, and/or viewing the video tutorial on this topic, you should be able to: understand the difference between Inverse functions and reciprocal functions , find an Inverse function by reversing the operations appliedtoxin the original function, find an Inverse function by algebraic manipulation, understand how to restrict the domain of a function so that itcan have an Inverse function, sketch the graph of an Inverse function using the graph of theoriginal outf 1by reversing the operations algebraic manipulation to work out Inverse graph off mathcentre 20091.

Inverse functions mc-TY-inverse-2009-1 An inverse function is a second function which undoes the work of the first one. In this unit we describe two methods for finding inverse functions, and we also explain that the domain of a function may need to be restricted before an inverse function can exist.
