Question

the domin of relation R on set N defined as R[X,Y]/X,Y€N, X+2Y=5]IS

PLEASE ANSWER IF YOUR GENIUS PLEASE​

Answer 1

Answer:

$.$

Step-by-step explanation:

R={ (x,y) / x,y ∈ N, x + 2y = 5}

x is the domain of the function

Domain ∈ Natural number

Range ∈ Natural number

x + 2y = 5

2y = 5 - x

y = \frac{5-x}{2}

f(x) = \frac{5-x}{2} ∵ y∈N

x < 5

If x is odd number then y ∈ N

If x is even nuber then y ∉ n

∴domain of f(x) = { 1 , 3 }
