### Instruction: help me answer this question Let R be the relation on Z defined by R = {(a, b): a, b ∈ Z, a – b is an integer}. Find the domain and range of R., think step by step
### Assistant: For question 3, since the difference between any two integers is always an integer, therefore, the domain and range of R is Z. , The answer is Domain of R = Z and Range of R = Z.
