22.5 Inverse-Proportion Functions in the Real World
Point 4 of 5
22.5.4 The Realistic Range of Values
Core idea
Headcount and length can't be negative, so you draw only the branch that makes sense and keep the domain grounded in reality.
Module goal. Use the inverse-proportion model to describe real quantities whose product stays fixed, building the model, solving it, and respecting the limits on the domain.
