This topic focuses on understanding and representing the domain and range of functions on a number line. It specifically challenges students to interpret statements about the domain or range (set of all real numbers described by certain conditions) and identify the correct graphical representation on a number line. The problems do not involve unions of intervals and progressively cover various situations like inequalities and specific bounds, aiding in introductory learning about the concepts of domain and range in functions. Each problem presents two visual answer options for students to select from.
