Option D:

The set is {-2, -1, 0, 1, 2, 3, 4}.

Solution:

Given set:


\{x \in Z:-2 \leq x \leq 4\}

Z means integer values.

Integer means set of positive and negative values including zero.


-2 \leq x \leq 4

This means x lies between -2 and 4.

  • If x strictly less than -2 and greater than 4 means you don't have to include -2 and 4.
  • But here x less than or equal to -2 and greater than or equal to 4, so you have to include -2 and 4.

The integers are -2, -1, 0, 1, 2, 3 and 4.

So, x belongs to the set {-2, -1, 0, 1, 2, 3, 4}

Hence the given set is defined by the set {-2, -1, 0, 1, 2, 3, 4}.

Option D is the correct answer.
