This math topic focuses on identifying whether given relations represent functions, visualizing these concepts at an introductory level. The problems are designed to help students understand and apply the definition of a function in the context of functions' domain and range. Each question provides two visual representations of relations, from which learners must determine which one qualifies as a function based on the criterion that each input in the domain is connected to exactly one output in the range.
