Question

Let A = (1,2,3,4} and B = {1,2,3,4) find the following (i) R = {(x, y) /x 2 y} (ii) R = ((x, y) / x = y?} 3.​

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}
