Solved Suppose \( G \) is a graph with vertices \( a, b, c,
WebThe graph has 6 vertices: a, b, c, d, e, and f. b. The adjacency matrix has a total of 12 ones, which represents the number of edges in the graph. However, each edge is counted twice in the matrix, once for each of its endpoints. Therefore, the actual number of edges is 6.
