complete bipartite subgraph of a graph
(a) prove that every graph of order $n \geq 4$ and size $n + 1$ contains $K_{1,3}$ as a subgraph

(b) describe the graphs of order $n \geq 4$ and size $n$ that do not contain $K_{1,3}$ as a subgraph

You should understand by now that this is not a homework service nor is it a tutorial service. Please either post some of your own work on these problems or explain what you do not understand about the question.
