Topic 5.12: Exploring Behaviors of Implicit Relations

Learning Objective: FUN-4.D

Determine critical points of implicit relations.

Essential Knowledge: FUN-4.D.1

A point on an implicit relation where the first derivative equals zero or does not exist is a critical point of the function.

Learning Objective: FUN-4.E

Justify conclusions about the behavior of an implicitly defined function based on evidence from its derivatives.

Essential Knowledge: FUN-4.E.1

Applications of derivatives can be extended to implicitly defined functions.

Essential Knowledge: FUN-4.E.2

Second derivatives involving implicit differentiation may be relations of x, y, and dy/dx.
