Please answer the following question.

Question 1

1.1

Explain why your two graphs are non-isomorphic. (b) Draw three non-isomorphic graphs with 4 vertices and 4 edges. Explain why your three graphs are non-isomorphic.(a) Draw two non-isomorphic graphs with degree sequence 3, 2, 2, 2, 1, 1, 1.decreasing order, is called the degree sequence of the graph. (a) Draw a graph with degree sequence 1, 1, 1, 4 or say why no such graph exists. (b) Draw a graph with degree sequence 1,1,1,1,4 or say why no such graph exists. (c) Prove that up to isomorphism, there is onlyr one graph with degree sequence 2,3, 3,1, 5,5. The list. of degrees of the vertieee of e graph1 arranged in 11011
