Q5 of 76 Page 2

Mark the correct alternative in the following:

If R = {(x, y) :x, yZ, x2 + y2≤ 4} is a relation on Z, then domain of R is


Domain of R is a set constituting all values of x.

Here, possible values for x by equation x2 + y2≤ 4 will be 0, 1, -1, 2, -2.


So, Domain of R is : {-2, -1, 0, 1, 2}.


Therefore, option C is correct.
