Yes, that is the right mindset towards to understanding if the function is odd or even. For it to be odd: j (a) = - (j (a)) Rather less abstractly, the function would. both reflect off the y axis and the x axis, and it would still look the same. So yes, if you were given a point (4,-8), reflecting off the x axis and the y axis, it would output ...Graph Theory - Fundamentals. A graph is a diagram of points and lines connected to the points. It has at least one line joining a set of two vertices with no vertex connecting itself.

Theorem 1.2 [20]In the complete graph, there is a big difference visually in using the spring-layout algorithm vs. the position dictionary used in this constructor. The position dictionary flattens the graph, making it clear which nodes an edge is connected to. But the complete graph offers a good example of how the spring-layout works.The signed complete bipartite graph Γ whose negative edges induce a 1-regular graph of different orders has been studied in [2].
