WebApr 14, 2024 · For real number \( x \) and \( y \), we write \( x R y \Leftrightarrow x-y+\sqrt{2} \) is an irrational number. Then the relation \( \mathrm{R} \) is.📲PW Ap... 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...

WebStep 1/2. (a) To determine whether C is reflexive, we need to check whether every element of R is related to itself under C. That is, we need to check whether xCx holds for every x∈R. For any x∈R, we have. x 2 + x 2 = 2 x 2, which is equal to 1 if and only if x^2 = 1/2. However, there are no real numbers x such that. WebFor every real number x and real number y, if x and y are both nonnegative, then their product is nonnegative. Let Q (x, y) be the statement "x has sent an e-mail message to y," where the domain for both x and y consists of all students in your class.
