Question

Let R : A to B , where A ={3,5},B = {7,11} and R ={ (a,b)€A×B, a-b is an odd number. write the relation of R

Answer 1

R={(3,7),(3,11),(5,7),(5,11)}
that is the relation of R
R sets ={3,5,7,11}

plz give me brainlist marks

Answer 2

Answer:

Mark me as brainliest and thank me if the answer is useful.

Step-by-step explanation:

A={3,5}  B={7,11}

R=(a,b):a∈A,b∈B,a−b is odd.

Let B=7,a=3

b−a=4, which is even.

Each element of B is odd & A also has odd elements.

Hence a−b is never be odd, it will always negetive even no.

Hence R=(a,b)∈ϕ.
