Question

If R = {(x, y): x + 2y = 8} is a relations in N, write
the range 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}

Step-by-step explanation:

Answer 2

Answer:

R(1,2,3)

Step-by-step explanation:

for x=2. y=3

for x=4. y=2

for x=6. y=1

R = {(2, 3), (4, 2), (6, 1)} Range = (1,2,3)
