Question

Let R be a relation of N defined by x+2y=8.The domain of R is
a) {2,4,8} b) {2,4,6,8} c) {2,4,6} d) {1,2,3,4}​

Answer 1

Answer:

c{2,4,6}

Step-by-step explanation:

because if we take these values we also get co-domain/range in N.

if we use 8 then we get 0 it's not N.

of we use 1 then we get rational number so it is also wrong.

so our domain is 2,4,6
