This math topic focuses on mapping set builder notation expressions to corresponding representations on a number line, specifically within the context of function domains and ranges. The problems require interpreting inequalities describing the sets of all real numbers \( \mathbb{R} \) that either satisfy a condition like \( X \leq 4 \) or fall within certain bounds like \( -9 \leq X < 2 \), and then choosing a correct graphical depiction on a number line. This set of problems helps reinforce understanding of domain and range concepts essential to the study of functions.
