• How do you find the maximum degree of a vertex on a graph?

  A vertex can form an edge with all other vertices except by itself. So the degree of a vertex will be up to the number of vertices in the graph minus 1. This 1 is for the self-vertex as it cannot form a loop by itself.

• What is the maximum degree for any vertex?

  The maximum degree of any vertex in a simple graph with n vertices is n-1. Explanation: - In a simple graph, each edge connects two distinct vertices and there are no loops or multiple edges. - The degree of a vertex is the number of edges incident to it, i.e., the number of edges connected to that vertex.
