What Is A Function

The video introduces the concept of functions, explaining how they transform inputs into outputs using mathematical notation like f(x). It covers calculating function values, solving for unknowns, and the rules that define valid functions. The video also explains domains and ranges, and concludes with a preview of future topics such as composite and inverse functions.
