Mathematics: Analysis and Approaches · SL / HL · syllabus-mapped notes

1. Functions, domain, range and notation

   What a function is, function notation such as $f(x)$, and how to read domain and range off a graph.

2. The inverse of a function

   The informal idea that $f^{-1}$ undoes $f$, and the inverse as a reflection in $y=x$.
