Question

find the domain and range of relation
R={(x,y) : y=x+ 6/x , x,y belong to N , and x is less than 6}

A) { 1,2,3} , { 7,5}
B) {1,2} , {7,5}
C) {2,3} , {5}
D) {7,5},{1,2,3}

​

Answer 1

Answer:

A

Step-by-step explanation:

if x is 1 then

y=1+6/1=7

if x is 2 then

y=2+6/2=5

if x is 3 then

y=3+6/3=5

if x is 4 then

y=4+6/4=11/2 this is not a Natural number so,

x=1,2,3 and

y=7,5
