11th Maths

From the following representation,write
(1) domain
(2) co-domain
(3) range of R
(4) the formula (relation between x and y)

where x belongs to A= { 1,2,3,4,5,6} and y belongs to B= {1,2,3,4,5,6}.

Pls answer this,
i will mark you brainlist,if you will be correct

Answer 1

Answer:

In domain and range of a relation, if R be a relation from set A to set B, then

• The set of all first components of the ordered pairs belonging to R is called the domain of R.

Thus, Dom(R) = {a ∈ A: (a, b) ∈ R for some b ∈ B}.

• The set of all second components of the ordered pairs belonging to R is called the range of R.

Thus, range of R = {b ∈ B: (a, b) ∈R for some a ∈ A}.

Therefore, Domain (R) = {a : (a, b) ∈ R} and Range (R) = {b : (a, b) ∈ R}

Answer 2

Answer:

Domain={1,2,3,4,5}

range of r={2,3,4,5,6}
