Question 1176595
.
TRUE or FALSE. ( 2 pts. Each)
~~~~~~~~~~~~~~



<pre>
1) Given { x Є R / -1 < x < 2 } then the solution set is { -1, 0, 1, 2 }.

         FALSE.


   The correct answer is  { all REAL numbers between -1 and 2, EXCLUDING endpoints }.


   The answer by @MathLover1 is INCORRECT at this part, since she missed to include all real numbers.



2) Given { x Є Z / -2 < x ≤ 1 }, the solution set is { -1, 0, 1 }.


         TRUE.



3) Let { x Є Z+/ -3 ≤ x < 3 }, the solution set is { 0,1,2 }.


         FALSE

          
        Z+ means positive integer numbers (greater than 0).
        The correct answer is  { 1,2 }.



4) Let { x Є Z-/ -5 ≤ x ≤ 1 }, the solution set is { -5, -4, -3, -2, -1}.


         TRUE


        Z- means negative integer numbers (less than 0).
        The answer is  { -5,-4,-3,-2,-1 }.



5) Let { x Є Prime nos. / 1 ≤ x ≤ 5 }, the solution set is { 1, 3, 5 }.


        FALSE.


        The correct answer is { 3,5 }.
</pre>
