Question

let A = {1,2,4,5,6,8} define a relation r from A to A by : R = {(x,y):x-y=2}
class 11

Answer 1

x-y=2

so we have to look at A ={1,2,4,5,6,8}

take random numbers which are given in the above set

x-y=2

take x=4 y=2 (x,y)=4,2

x=8 y=6 (x,y) = 8,6

x=6 y=4 (x,y)= 6,4

so the

R={ (4,2) (8,6) (6,4)}

so this is the answer for your question
