Question

The solution set for the following number line is:

Options

• {x : x ∈ Z and – 3 < x < 4}

• {x : x ∈ Z and – 3 ≤ x}

• {x : x ∈ Z and – 2 ≤ x ≤ 4}

• {x : x ∈ Z and – 3 ≤ x ≤ 4}

Answer 1

{x : x ∈ Z and – 3 ≤ x ≤ 4}

Explanation:

Since there are dark dots at

x = –3, –2, –1, 0, 1, 2, 3, 4

So, all there points are included in the solution set.

∴ Solution set = {x : x ∈ Z and – 3 ≤ x ≤ 4}
