In part A both graph are not isomarphism ,reason behind it is they have not equal vertices.
In part B Graphs are isomorphic as they fulfill all properties.

Determine whether the given pair of graphs is isomorphic, if the graphs are not isomorphic provide an argument? A) F G B) 4) Consider the following weighted graph G below
3. For each pair of graphs, determine whether or not they are isomorphic. If they are isomorphic, write down an isomorphism between them (a map between vertices that extends to a map between edges). If they are not isomorphic, give a graph invariant that distinguishes them. 1 b 5 11 (b)

If they are not isomorphic, give a graph invariant that distinguishes them. d 3 2 b (a) a 2 4 7 h (b)
2. a) Determine whether the following graphs are isomorphic or not. If so write an isomorphism, if not explain why. 1 b 2 a 6 3 f d 5 4 e Graph A Graph B. b) Is the graph A bipartite. If not, find a vertex v such that A - v bipartite? c) Does the graph A have an Eulerian circuit? If not find an edge e such that A - e has an Eulerian circuit.
(c) Determine whether the given pairs of graphs are isomo or provide a rigorous argument that none exists. Answer:
10. Two of the graphs in Figure 1.25 are isomorphic. FIGURE 1.25 (a) For the pair that is isomorphic, give an appropriate one-to-one corre- spondence (b) Prove that the remaining graph is not isomporhic to the other two
Homework Problems Problem 12.8. Determine which among the four graphs pictured in Figure 12.24 are isomorphic. For each pair of isomorphic graphs, describe an isomorphism between them. For each pair of graphs that are not isomorphic, give a property that is preserved under isomorphism such that one graph has the property, but the other does not. For at least one of the properties you choose, prove that it is indeed preserved under isomorphism (you only need prove one of them)...
1. Draw all non-isomorphic simple graphs with 5 vertices and 0, 1, 2, or 3 edges; the graphs need not be connected. Do not label the vertices of your graphs. You should not include two graphs that are isomorphic. 2. Give the matrix representation of the graph H shown below. 3. Question 3 on next page. Place work in this box. Continue on back if needed.
