Which inequality is represented by this graph?

Question 2 options:

-3 ≤ x ≤ 3


-3 < x < 3


-3 ≤ x < 3


-3 < x ≤ 3

Answer 1

Opt. 1 -3 ≤ x ≤ 3

Explanation:

Inequalities are regions, the attached picture shows us a region located between -3 and 3, the dots used are solid, this means that the value '3' is include in the region.

Hence the variable is narrowed to -3 and 3.
