Question
(a) Find the connected components of cach graph.
(1) G = (V, E). V= {a, b, c, d, e}. E= @
(ii) G = (V, E). V = {a, b, c, d, e, ƒ}. E= {{c, S}, {a, b}, {d, a}, {e, c}, {b, S}}
(b) Determine the edge connectivity and the vertex connectivity of cach graph.
Figure 7: An undirected graph has 8 vertices, 1 through 8. 4 ver-
tices form a rectangular-shape on the left. Starting from the top left
vertez and moving clockwise, the vertices of the rectangular shape are,
1, 2, 3, and 4. 3 vertices form a triangle on the right, with a vertical
side on the left and the other verter on the extreme right. Starting
from the top vertez and moving clockwise, the vertices of the triangu-
lar shape are, 7, 8, and 5. Vertez 6 is between the rectangular shape
and the triangular shape. Undirected edges, line segments, are between
the following vertices: 1 and 2; 2 and 3; 3 and 4; 4 and 1; 2 and 6; 4
and 6; 3 and 6; 6 and 7; 6 and 8; 6 and 5; 7 and 5; 7 and 8; and 5
and 8.

Expert Solution
Step 1

Answer for  sub question a:

Given graph is, G=V,E,V=a,b,c,d,e, E=

1) Note: A vertex with no incident edges is itself a component. 

Since the given graph has no edges, no edges are incident on any of the vertices.

Therefore, each vertex is a component.

Therefore, number of components in the given graph is 5.

Step 2

2) The given graph is

G=V,E , V=a,b,c,d,e,f, E=e,fa,b,d,a,e,c,b,f

First draw the graph.
