Question

write the relation R given below in roster form R={(x, 1-x) :x£A}
where ={-2,-1,0,1,2​

Answer 1

Answer:

By definition of the relation,

R = {(1, 3), (2, 6), (3, 9), (4, 12)}

Hence, the corresponding arrow diagram is as follows:

Relation and Function Exercise 2_1

The set of first element, i.e. the domain = {1, 2, 3, 4}

Similarly, the set of second elements, i.e. the range = {3, 6, 9, 12}

And the co-domain = {1, 2, 3, ….. 14}
