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.
Here is a picture of an octahedron, which is a regular (Platonic) solid with 8 triangular faces, 12 edges, and 6 vertices. You can imagine an octahedron as two pyramids with square bases, which are then glued together along their bases. octahedron We can turn a polyhedron into a graph by placing its vertices in the plane, and adding edges between those vertices which share an edge on the solid. If we do this to the octahedron, we get the...
Does there exist a set of intervals, no 5 of which share a point, such that the interval graph (this is the graph formed by taking the vertices to be the intervals, and then you connect two of the vertices by an edge if the corresponding intervals intersect) is non-planar? Prove or disprove. Please do not just give the definition of interval graphs as others have for this same question.

For each k2 1 construct a graph which is regular with degree 2k+1 and does have a bridge. (Hint: There is a solution with diameter 5. Start with k = 1 then try to generalize. You are also welcome to give a construction with a larger diameter.) make sure I can understand your construction and draw it for me in the case k = 2.

G1: I can create a graph given information or rules about vertices and edges. I can give examples of graphs having combinations of various properties and examples of graphs of special (" named”) types. 1. Draw a graph G with • V(G) = {a,b,c,d,e,f}, • deg(d) = 2, • a and f are neighbors, • {b,d} & E(G), G is simple, • K4 is a subgraph of G. 2. Draw the graph C7. 3. Answer each question about the graph...
