Graph relational algebra
WebIn this case, this is a function because the same x-value isn't outputting two different y-values, and it is possible for two domain values in a function to have the same y-value. If you graph the points, you get something that looks like a tilted N, but if you do the vertical line test, it proves it is a function. WebMathematical background. Barry DwyerBarry Dwyer, in Systems Analysis and Synthesis, 2016. Abstract. Mathematical Background presents the ideas from propositional calculus, predicate calculus, binary relational algebra, and graph theory that dominate the book. Graphs are a way of representing relations that is better suited to the human visual …
