This topic focuses on identifying functions from relations using visual relation maps. Specifically, it evaluates whether a relation qualifies as a function based on the criteria that every \( x \) value in the relation maps to a unique \( y \) value. The questions guide students to discriminate between relations where each \( y \) value corresponds to a single \( x \) value and those that follow the correct function criterion, reinforcing foundational understanding of functions related to domain and range.
