Hints:
3. Think about any graphs G for which there exists a constant c such that ex(n, G) = ex(m, G) for all integers m, n > c. Is there a simple way to modify these graphs so that they have the same property (possibly with a different value of c)? Be careful to prove that you have found all of the graphs. ex (n,H) = max number of edges in any graph of order n
So basically If you create any graph G with n vertices, there can be no subgraph of G which is isomorphic to H or else G contains H and is not H-free
