Graph Behavior and Mathematical Concepts

Miss Kos reviews multiple choice questions written by Mr. Passwater, focusing on graph analysis, water container problems, and skydiving scenarios. She discusses concepts like constant rate, concavity, and inflection points, while also addressing updates to the questions and encouraging feedback.
