Given the domai

Solution

a If x is even then x>0.

Truth set = {32,42}

---------------------------------

i) There exists an x in domain D, such that the ones digit is 2 and the tens digit is 3 or 4

True because 42, 32 are digits satisfying this.

ii) ) For all x in domain D, if the ones digit is 2 then the tens digit is 3 or 4.

False because 22, 12 are also two digits without satisfying the above condition
