Question

3. Let A = (6, 7, 8, 10), B = (2,4,5), a e A,b e B and R be the relation from A to B defined by
a R b if and only if a is divisible by b. Write R in the roster form.​

Answer 1

Answer:

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}
