Question

Given: r = (√3, √5, √7, √13) Why is r not a relation?

Answer 1

Answer:

Option B.

Step-by-step explanation:

Given:

$r=(\sqrt{3},\sqrt{5},\sqrt{7},\sqrt{13})$

r is a set of rational numbers.

We need to find the reason why r is not a relation.

A relation is a set of ordered pairs, where x-coordinate is domain and y-coordinate is range. It is defined as

$R=\{(a,b):a\in R,b\in R\}$

Since r is not a set of ordered pairs, therefore r is not a relation.

Thus, the correct option is B.
