a. With 4 vertices we can not get the cover G. As ther are 4 pair wise non-adjacent vertices . We need atleast 4 vertices from there means , out of those 8 verices we need atleast 4 vertices and from left 4 vertice we need atleast 1 vertex to cover G.
So one of the possible Cover of G will {a,c,e,g,i}.
So, the answer will be No.
b.For a cover of a Graph , by defination the cover will be the set or sub set of all the vertex of a graph.
For by defination atmost we can take all the 12 vertices as the cover of G.

A graph (G) with 12 Vertices has 4 PAIR-WISE non-Adjacent Vertices, What could be said for its Minimum Vertex Cover of G? at Least 4 vertices (Yes, No, Impossible to determine?) b) at Most 8 vertices (Yes, No, Impossible to determine?)
Draw a Graph with 12 vertices which has 4 pair-wise nonadjacent vertices.
Let G be a non-Hamiltonian, connected graph. For every pair of nonadjacent vertices u and v, 8(u) +8()2 k, for some k> O. Show that G contains a path of length k.

PLEASE HELP Let G is a graph with 2n vertices and n^2 edges. An amicable pair of vertices is an unordered pair (u, v), such that dist(u, v) = 2. Prove that G has at least n(n − 1) amicable pairs of vertices.
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.

Say that we have an undirected graph G(V, E) and a pair of vertices s, t and a vertex v that we call a a desired middle vertex . We wish to find out if there exists a simple path (every vertex appears at most once) from s to t that goes via v. Create a flow network by making v a source. Add a new vertex Z as a sink. Join s, t with two directed edges of capacity...
Draw a simple undirected graph G that has 12 vertices, 18 edges, and 3 connected components. Why would it be impossible to draw G with 3 connected components if G has 66 edges?
