22.3 Properties of the Inverse-Proportion Function
Point 3 of 6
22.3.3 Symmetry About the Center
Core idea
Spin the graph a half-turn around the origin and the two branches swap places exactly, so the hyperbola has central symmetry about the origin.
Module goal. Read off increase/decrease behavior, symmetry, and the geometric meaning of k straight from the graph, matching each property to its picture.
