At the left end of each interval, use [ with each end value to be included in the set (solid dot) or ( for each excluded end value (open dot).WeBWorK: Entering Two Inequalities or Two Intervals. For x < − 2 or x > 2: For inequality notation type x < -2 or x > 2. Be sure to include the word "or" between the solutions. For interval notation, the upper case "U" means that values from either interval are solutions: (-inf, -2) U (2, inf). 🔗.Denote this idea with an open dot on the number line and a round parenthesis in interval notation. Example 1: Graph and give the interval notation equivalent: x < 3. Solution: Use an open dot at 3 and shade all real numbers strictly less than 3. Use negative infinity The symbol (−∞) indicates the interval is unbounded to the left.

A closed interval [a, b] represents the set of all real numbers x such that a ≤ x ≤ b. Example: [ 2, 7] is a closed interval which includes 2, 7 and all the real numbers between 2 and 7. We can write it with the help of compound inequality 2 ≤ x ≤ 7.
