This math topic focuses on determining the range of quadratic functions by identifying either the minimum or maximum \( y \)-values. The problems are framed by providing the max or min \( y \)-value, and students are tasked with selecting the correct range from multiple choices, all presented in interval notation. The topic is part of a broader introduction to quadratic equations and their vertex forms, aiming at enhancing comprehension of how \( y \)-value extremities influence the range of quadratic functions. Each question is structured with given extremities and associated potential range options to analyze.
