Question

If A = {x, y, z), B = {p, q, r, s) which of the relation on A to B are function.
(a) {n, p), (x, q), (y, r), (z, s)}, (b) {( x, s), (y, s), (z, s)}
(c) y, p), (y, q), y, r),(z, s),
(d) {(x, p), (y, r), (z, s)}
​

Answer 1

Step-by-step explanation:

(A) .(C)

If R is a relation from A to B, then R ⊂(A×B) which consists of all ordered pairs of the type. (x, y) such that x∈A,y∈B.

Clearly, R

1

and R

3

are such sets of A×B. The elements (q, b), of R

2

∈(B×A)and not A×B and the elements (q, b), and (s, b), of R

4

also not belong to A×B and as such R

2

and R

4

are not relations from A to B.
