Question

Let A = {1,2,3,4,5,6,7,8 and R be
the relation on A define by
R = {(x, y): x € A, y e A and x + 2y =
10) Write the R in roster form find the
domain, co-domain and range of theR​

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}
