A graph is k-critical if x(G) = k and if the deletion of any vertex yields a graph with smaller chromatic number. The chromatic number is the minimum number of colors needed for a vertex coloring of the graph. (a) Find all 2-critical and 3-critical graphs. (b) Give an example of a 4-critical graph. a
