Use Euler's theorem to determine whether the graph has an Euler path (but not an Euler circuit), Euler circuit, or neither. в A D F E

Refer to the figure below. a. Find a closed path of length 4 starting at vertex v2. b. Find a cycle of length 5 starting at vertex V1. c. Find a circuit that is not a cycle at vertex V4. VI V6 V5 V2 VA V 3

For the following graph, explain, giving reason for your answer, why an Euler circuit exists. Indicate the circuit. a 8 e h j

Is it possible for a graph to have both a Euler path and Euler circuit? Explain your answer.
