Precalculus Functions Unit Part 1: Equations as Real Valued and Boolean Functions

This video was made possible by the UW's Robinson Center for Young Scholars to help our students and students more broadly learn precalculus.

Functions are the critical concept of precalculus. We aim to emphasize the machine-like nature of functions. In particular, they associate each input with some well-defined output. Aside from this input-output structure, functions are extremely flexible in their construction and conceptualization. In this unit, we model a variety of different viewpoints for thinking about functions.
