Identify Functions From Ordered Pairs

Identify functions from ordered pairs with this eighth-grade algebra worksheet! In math, a relation can be categorized as a function if every input value has exactly one output value. Featuring 14 sets of ordered pairs, this one-page practice worksheet asks students to determine if each relation, or set of ordered pairs, is a function. Being able to identify functions from ordered pairs is an important foundational step for learning about specific types of functions, such as linear functions.
