Question

Let A = {1, 2, 3, 4, 6} and R be a relation on A
defined by aRb if and only if ‘a’ is a multiple of b.write the relation for it

Answer 1

Answer:

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

Step-by-step explanation:

To find the domain and range, we simply solve the equation y = f(x) to determine the values of the independent variable x and obtain the domain. To calculate the range of the function, we simply express x as x=g(y) and then find the domain of g(y).

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}
