Relationships are represented as ordered pairs, tables, mapping diagrams, and graphs. For instance, x is an object of set A and y is an object from set B. 4.2 Relations and Functions A function is a relation in . If any of the x values are repeated, but the values that correspond to them in the y-axis are different, then we are dealing with a relation rather than a function.
