Answer 1

Answer:

$A={1,2,3,4,6}</p><p></p><p>R={(a,b):a,b∈A,b is exactly divisible by a}</p><p>(i) R={(1,1),(1,2),(1,3),(1,4),(1,6),(2,2),(2,4),(2,6),(3,3),(3,6),(4,4),(6,6)}</p><p>(ii) Domain of R={1,2,3,4,6}</p><p>(iii) Range of R={1,2,3,4,6}</p><p></p><p>$

Answer 2

A={1,2,3,4,6}

R={(a,b):a,b∈A,b is exactly divisible by a}

(i) R={(1,1),(1,2),(1,3),(1,4),(1,6),(2,2),(2,4),(2,6),(3,3),(3,6),(4,4),(6,6)}

(ii) Domain of R={1,2,3,4,6}

(iii) Range of R={1,2,3,4,6}
