Question

For the relation S {(x,y) / x + y = 7, Y belongs to N}Range is ___​

Answer 1

Answer:

[1,6]

Step-by-step explanation:

since

x+y=7

therefore all the elements or no which satisfy y in the equation are it's range.

so when x is 1, y is 6

so when x is 2 , y is 5

when x is 3 , y is 4

when x is 4 , y is 3

when x is 5 , y is 2

when x is 6 , y is 1

so it's range is from 1 to 6
