Question

Let f = {(x,y) | x,y € N and y = € N and y = 2x} be a relation on N. Find the

domain, co-domain and range. Is this relation a function?​

Answer 1

answer  is this only i think

Step-by-step explanation:

Answer

Given R={x,y):y=2x;x,y∈N}

Domain of R = set of natural numbers Co-domain of R= set of natural number  

Range of R= set of even natural numbers  

Clearly, every natural number is related to unique image, so this relation is a function.
