Unformatted text preview: ( x = y 2 ): (False) Suppose x = a satises the above statement. This means that a = y 2 for all real values of y . This is impossible since y would then be equal at most 2 real values ( a ). 2. x y ( xy = 0): (True) At x = 0, xy = 0 for all real values of y . 3. x n =0 y xy = 1: (True) If we pick an arbitrary value for x n = 0, say a , then there exists a value for y that satises the given statement, y = 1 a . 4. x y ( x + y n = y + x ): (False) The addition of real numbers is always commutative operation. 2...
