Question

Q.7
if
R = {(x, y) :X + 2y = 8} is a relation
of natural number condomain
relation on set
of R.
​

Answer 1

Answer:

x+2y=8 , Given x,y are natural numbers , which implies x,y>0

If y=1 , we get x=6

If y=2 , we get x=4

If y=3 , we get x=2

For y≥4 , x wont be a natural number

So the range of R is {1,2,3}
