# Draw the directed graphs of the relations defined in 13-18.Let A = { 2 , 3 , 4 , 5 , 6 , 7 , 8 } and define a relation T on A as follows: For every x , y ∈ A , x V y                   ⇔     5 | ( x 2 − y 2 ) .

To determine

Draw the directed graph of the relation.

Explanation

Given information:

For all x,yA, define a relation V on A follows:

A={0,1,2,3,4,5,6,7,8}, x V y5|(x2y2)

Calculation:

Thus the relation R is then:

V={(0,0),(0,5),(1,1),(1,4),(1,6),(2,2),(2,3),(2,7),(2,8),(3,2),(3,3),(3,7),(3,8)       (4,
