Question

Given A = {2, 4, 6, 8, 10}, B = {5, 3, 2, 1, 0} and a relation R from A to B such that R = {$(x,y):xϵA,yϵBandx+y=7$}. Find R.

Answer 1

For the required Relation we have to find the ordered pairs where $x$ co-ordinate is from set A and $y$ co-ordinate from set B such that $x+y=7$
So, the relation is $R=\left\{\right(2,5),(4,3),(6,1\left)\right\}$ .
