WebOct 27, 2016 · Sorted by: 1. The domain is probably meant to be the set of objects that are the possible first elements of the pairs in R, and the co-domain the set of objects that are the possible second elements of the pairs in R. So, since you have a 1, 2, and 3 as possible first (or 'left') elements, the domain is { 1, 2, 3 }. Same for the dodomain. WebCS 441 Discrete mathematics for CS M. Hauskrecht Combining relations Definition: Let A and B be sets. A binary relation from A to B is a subset of a Cartesian product A x B. R t•Le A x B means R is a set of ordered pairs of the form (a,b) where a A and b B. Combining Relations • Relations are sets combinations via set operations
