Identifying Functions

About these worksheets

Students learn to identify whether a relationship is a function using equations, graphs, and tables. Activities include applying the vertical line test to graphs, checking if each input has exactly one output in tables, finding points that belong to a given function, and matching function equations to tables. Aligned with eighth grade standards.
