Question

Let R be relational to N defined by X+2Y = 8, find R , R-1 question is from calss 11th chapter Relations and Functions. please answer correctly.

Answer 1

Answer:

x+ 2y= 8

x= 8− 2y

Since y and x both must be natural,

Possible values of y are 1,2,3 which corresponds to possible value of y to be 6,4,2 .

Thus range of R = {2,4,6}

Answer 2

Answer:

x+2y=8

x=8−2y

Since y and x both must be natural,

Possible values of y are 1,2,3 which corresponds to possible value of y to be 6,4,2 .

Thus range of R = {2,4,6}
