Question

A=(1,2,3,5) and B=(4,6,9) define a relation from A to B such that x-y is even.write R in roster form​

Answer 1

Answer:

Relation from A to B ={(1,9), (2,4), (2,6), (3,9), (5,9)}.

Step-by-step explanation:

A = (1,2,3,5) and B = (4,6,9)

so, R = { (1,4), (1,6), (1,9), (2,4), (2,6), (2,9), (3,4), (3,6), (3,9), (5,4), (5,6), (5,9) }

Now, according to question relation from A to B such that x-y is even are

=> { (1,9), (2,4), (2,6), (3,9), (5,9) }.
