WebJun 11, 2024 · Matrix Representations 1 WebJust like a relation, a function is also a set of ordered pairs; however, every x x -value must be associated to only one y y -value. Suppose we have two relations written in tables, A relation that is not a function. Since we have repetitions or duplicates of x x -values with different y y -values, then this relation ceases to be a function.
