For each of the following graphs draw a planar representation or show that it has a subgraph homeomorphic to K; or K3,3: (a) (b) (c) (d)
3. For each of the following graphs, determine if the graph is planar. If it is, draw a plane representation of the graph; if not, indicate a subgraph homeomorphic to Kor K3,3 G
3. Vertex Cover on Planar Graphs. The problem Planar Vertex Cover is to find a smallest set C of vertices in a given planar graph G such that every edge in G has at least one endpoint in C. It is known that Planar Vertex Cover is NP-hard. Develop a polynomial time approximation scheme (PTAS) for the problem.

2 (a) Draw the graphs K5,2 and K5,3 using the standard
arrangement.
For example, K5,2 should have a row of 5 vertices above a row of
2 vertices, and the edges connect each vertex in the top row to
each vertex in the bottom row.
(b) Draw K5,2 as a plane graph, i.e., with no edges
crossing.
(c) Complete the following table, recalling E is the number of
edges in a graph and V is the number of vertices. (Strictly...
