Bellwork gave students practice determining if the inverse of a given relation is a function or not.  They also practiced restricting the domain of a quadratic functions so that the inverse becomes a function, and listing the resulting range.

The remainder of the period we finished our discussion on Topic 2 by finding the vertex of parabolas in order to make restrictions on quadratic functions so that their inverses become functions.  Students were also introduced to the geometric definition of a parabola and how that relates to real-world uses of parabolic shapes.
