This math topic focuses on identifying the domain of simple quadratic functions and representing them on a number line. Each problem presents a quadratic function equation and asks learners to select the correct domain representation on a number line. It provides an opportunity to practice understanding the function's behavior and determining its domain visually. This set of problems is a fundamental exercise in linking quadratic equations and their graphical interpretations, enhancing skills in analyzing algebraic functions and applying them to numerical ranges.
