22.3 Properties of the Inverse-Proportion Function
Point 2 of 6
22.3.2 The Trap of Comparing Across Branches
Core idea
You can't directly compare sizes between the two branches, so be careful crossing the break at x=0 and don't just assume.
Module goal. Read off increase/decrease behavior, symmetry, and the geometric meaning of k straight from the graph, matching each property to its picture.
