3. Find a graph with the given set of properties or explain why no such graph can exist. The graphs do not need to be trees unless explicitly stated. (a) tree, 7 vertices, total degree = 12. (b) connected, no multi-edges, 5 vertices, 11 edges. (c) tree, all vertices have degree <3, 6 leaves, 4 internal vertices. (d) connected, five vertices, all vertices have degree 3.
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.

Please answer question 2. Introduction to Trees Thank you 1. Graphs (11 points) (1) (3 points) How many strongly connected components are in the three graphs below? List the vertices associated with each one. 00 (2) (4 points) For the graph G5: (a) (0.5 points) Specify the set of vertices V. (b) (0.5 points) Specify the set of edges E. (c) (1 point) Give the degree for each vertex. (d) (1 point) Give the adjacency matrix representation for this graph....
Recall the definition of the degree of a vertex in a graph. a) Suppose a graph has 7 vertices, each of degree 2 or 3. Is the graph necessarily connected ? b) Now the graph has 7 vertices, each degree 3 or 4. Is it necessarily connected? My professor gave an example in class. He said triangle and a square are graph which are not connected yet each vertex has degree 2. (Paul Zeitz, The Art and Craft of Problem...
Answer each question in the space provided below. 1. Draw a simple graph with 6 vertices and 10 edges that has an Euler circuit. Demonstrate the Euler circuit by listing in order the vertices on it. 2. For what pairs (m,n) does the complete bipartite graph, Km,n contain an Euler circuit? Justify your answer. (Hint: If you aren't sure, start by drawing several eramples) 3. For which values of n does the complete graph on n vertices, Kn, contain a...

can you please do all question #1? Answer each question in the space provided below. 1. Consider the tree shown below: (a) Give the order in which the vertices of the tree are visited in a post-order traversal. You may assume all children are ordered from left to right. (b) Give the order in which the vertices of the tree are visited in a pre-order traversal. You may assume all children are ordered from left to right. 2. Question 2...
1. You will be asked questions about graphs. The graphs are provided formally. To answers the questions, it may help to draw the graphs on a separate sheet. a Consider the graph (V, E), V = {a,b,c,d) and E = {{a,d}, {b,d}, {c, d}}. This graph is directed/undirected This graph is a tree y/n. If yes, the leafs are: This graph is bipartite y/n. If yes, the partitions are: a, d, b, c is/is not a path in this graph....
