Use Graphs \(I\) and \(/\) in Figure 12.301 to answer each question.

1. Which vertices are in each of the components that remain when edge \(j\) / is removed from Graph \(ho\) ?

2. Determine the number of edges and the number of vertices in Graph I. Explain how this confirms that Graph \(I\) is a tree.

3. What kind of cycle is created if edge cf is added to Graph??
