Q. 384.3( 3 Votes )

State True

Class 11th Mathematics - Exemplar 2. Relations and Functions

Answer :

The given statement is false.

Explanation:

given R = {(x, y) : y = x – 5, x, y ∈Z}

This means set R contains numbers such that y = x-5, so

So when x = 5, y becomes

y = x-5 = 5-5 = 0

So corresponding y will be 0,

So (5,2) does not belong to R.
