Determine whether each graph has directed or undirected edge

Determine whether each graph has directed or undirected edges, whether it has multiple edges, and whether it has one or more loops. Determine the type of graph based on Table One from p.644 of the text.

A)

B)

C)

Solution

graph A) is a multygraph because undirected edges multiple edges and loops are not allowed

graph B) is undirected simple graph

graph C) isdirected multygraph
