Question

If A ={1,2,3,5} and B = {4,5,9}. Define a relation R from A to B by R = {(x,y): the difference between x and y is odd, x belongs to A and y belongs to B}. Write R in Roster form.

Answer 1

Answer:

A={1,2,3,5} and B={4,6,9}

R={(x,y): the difference between x and y is odd x∈A,y∈B}

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