A complete bipartite graph, sometimes also called a complete bicolored graph (Erdős et al. 1965) or complete bigraph, is a bipartite graph (i.e., a set of graph vertices decomposed into two disjoint sets such that no two graph vertices within the same set are adjacent) such that every pair of graph vertices in the two sets are adjacent. If …A graph with an odd cycle transversal of size 2: removing the two blue bottom vertices leaves a bipartite graph. Odd cycle transversal is an NP-complete algorithmic problem that asks, given a graph G = (V,E) and a number k, whether there exists a set of k vertices whose removal from G would cause the resulting graph to be bipartite. The problem is …To find the x -intercepts, we can solve the equation f ( x) = 0 . The x -intercepts of the graph of y = f ( x) are ( 2 3, 0) and ( − 2, 0) . Our work also shows that 2 3 is a zero of multiplicity 1 and − 2 is a zero of multiplicity 2 . This means that the graph will cross the x -axis at ( 2 3, 0) and touch the x -axis at ( − 2, 0) . 1.
