This math topic focuses on defining the domain and range of functions from representations on a number line to interval notation. It involves interpreting graphical number line representations and translating these into interval notation, including unions of intervals. The problems ask learners to select the correct interval notation that represents given segments or gaps on the number lines, enhancing their understanding of how domain and range are visually and numerically expressed in function analysis.
