Mapping diagrams can provide a coherent framework for developing a sensible visual approach for learning and teaching function concepts starting from basic arithmetic through the key ideas of algebra and culminating with calculus, complex analysis, and linear algebra. The author will present many recently created figures for linear functions in a variety of contexts demonstrating how mapping diagrams enhance their study by providing visualizations for many fundamental concepts. Dynamic figures created with GeoGebra are included.
