I am looking at the following problem:
Define $V=\{0,1,2,3,4,5\}$. Define a graph $G=(V,E)$ by letting the edges be: $$ E =\{(a,b):a-b^2 \le 1 \lor b-a^2 \le 1\}$$
I understand that 'V' stands for vertext and 'E' stands for edge -- but how do you actually take this information and construct a graph? It looks like the question gives you six individual vertexes to start out with.
