Question

1. If A = {4, 6, 8, 10), B = {2, 3, 4, 5). R is a relation defined from A to B
where R= {(a,b): a EA, DEB and a is a multiple of b)
find (R in the Roster form (ii) Domain of R (iii) Range of R.​

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}

I think it will help uh....

Answer 2

Answer:

ii)Domain of R (1,2,3,4,5,6,)

iii) Range of R(1,2,3,4,5,6,)

ok I think this answer is right
