Consider a bipartite graph on the set A = {1,2,3,4,5,6} and B = {7,8,9,10,11,12}, where there is an edge between xe A and y e B if and only if x+y is a multiple of 4. What is the size of N({2})? What is the size of N({2,5})? What is the size of N({2,6})? Is there a matching in this graph?

Expert Solution
Step 1
Given:
A bipartite graph is defined on set A={1,2,3,4,5,6} and
B={7,8,9,10,11,12}.
Here there is an edge between and if and only if x+y is multiple of 4.
The edges will be between the set of points (x, y):
(1, 7), (1, 11), (2, 10), (3, 9), (4, 8), (4, 12), (5, 7), (5, 11), (6, 10)
