Recall that a bridge in a connected graph is an edge whose removal disconnects the graph. The maximum number of edges in a graph on 10 vertices that contains a bridge is _______.

Explain thoroughly!!

Discrete math. Graph theory

Decide whether the pair of graphs are isomorphic or not. If they are isomorphic find an isomorphic mapping between them. If they are not isomorphic find one specific property in which they differ. (name the vertices of given graphs)

4. Determine if the following graphs are isomorphic or not? If yes, show how are they isomorphic. If not also explain your justification. (hint: You can label your vertices)

If the graph G has exactly three components, then the number of components of K| UG is
