For 8th Grade students, domain and range is an important topic because it is essential for future studies in mathematics, including calculus and higher-level algebra. “Identify domain and range practice problems” can help students build a deeper understanding of the domain and range of a relation.
This practice includes questions in which students must determine the domain and range of a relation given by a graph, a mapping diagram, or ordered pairs. By solving these problems students become more comfortable with identifying domains and ranges.
