Overview of one to one functions

The video tutorial explains the concept of functions, focusing on one-to-one functions where each element in the domain maps to a unique element in the range. It uses mapping tools and graphical analysis to illustrate these concepts, highlighting the differences between general functions and one-to-one functions. The tutorial also discusses why parabolas are not one-to-one and the significance of one-to-one functions in understanding inverses.
