e) A vertex cover is a set of vertices for which each edge has at least one of its vertices in the set. What is the size of the smallest vertex cover in the Petersen graph? Give example of much as an f) Prove that a smaller set does not exist. g) A dominating set is a set of vertions for which all other vertices have at least one neighbor in this set. What is the size of the smallest dominating set in the Petersen graph? Give an example of such a se ) Prove that a smaller set does not exist.
