WebAnswer (1 of 4): For every value of x belongs to R, x-x + \sqrt{2} i.e. \sqrt{2} is an irrational number. Therefore, it is reflexive. Now let’s say x = \sqrt{2} and y = 2 then, x - y + \sqrt{2} = 2\sqrt{2} - 2 which is irrational but when y = \sqrt{2} and x = 2, x - y + \sqrt{2} is not irrati...
