Question

let r be a relation on z defined by R= {(a,b):a belongs to z b belongs to z,a^2=b^2} find (a) domain of r (b) range of r​

Answer 1

Answer:

Mark me as brainlist.

Step-by-step explanation:

The relation R on Z is defined by  

R={(a,b):a,b∈Z,a−b is an integer}

Since a−b is an integer for all a, b∈Z.  

So, Domain (R)=Z, Range (R)=Z.
