1. Problem: Find the end vertices of edge e8 in the given graph. 2. Given: Edge e8 connects vertex V2 and vertex V5. 3. Explanation: The end vertices of an edge are the two vertices that the edge connects. 4. Therefore, the end vertices of e8 are $V2$ and $V5$. Final answer: End vertices of e8 are $V2$ and $V5$.
