The following statements are about the chromatic number x(G) and the chromatic index x'(G) of graphs. We use A(G) for the maximum degree of G. Determine whether each of the following statements is true or false. True 1. For all n ≥ 3, x'(Cn) = A(Cn). False 2. In any bipartite graph G, x'(G) = 2. 3. In any bipartite graph G, X(G) = 2. True ✓4. For all n > 3, x'(Pn) = A(Pn). False True 5. If a graph contains a vertex of degree 3, then the chromatic number of the graph is at least 3.
