These points can be described the following double inequality: -3≤x≤13.
Inequalities
Inequality is a mathematical expression that does not present equality between both sides. It is represented by symbols: <, ≤, > and ≥.
When the variable x is between the both extremes, the inequality will be called double inequality. Therefore, the double inequality can be written in the form below .
- a<x<b is equivalent to x>a and x<b
- a>x>b is equivalent to x<a and x>b
- a≤x≤b is equivalent to x≥a and x≤b
- a≥x≥b is equivalent to x≤a and x≥b
As the interval is represented by a closed dot, your interval inequality must be represented by signs ≤ or ≥.
Thus, the points of this question can be described as: -3≤x≤13.
