TRUE or FALSE. ( 2 pts. Each)
1.) Given { x Є R / -1 < x < 2 } then the solution set is { -1, 0, 1, 2 ].->FALSE
reason: and should be excluded and the solution set is ( -1, 0, 1, 2 )
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
reason: includes all numbers equal and greater to and less than and the solution set is { -3, -2, -1, 0, 1,2}
4.) Let { x Є Z-/ -5 ≤ x ≤ 1 }, the solution set is { -5, -4, -3, -2, -1}.->FALSE
reason: so it includes all numbers from to and the solution set is { -5, -4, -3, -2, -1,0,1}
5.) Let { x Є ->FALSE. / 1 ≤ x ≤ 5 }, the solution set is { 1, 3, 5 }.->FALSE
reason:
List of prime some numbers: , , , ,.....

TRUE or FALSE. ( 2 pts. Each)
~~~~~~~~~~~~~~
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 }.
Solved.
