WebBefore we formally define interval notation, we should note that sometimes we want to include the endpoints in our set. To do this, we introduce the notation [0, 2], which is equivalent to the inequality 0 ≤ 𝑥 ≤ 2. In other words, it is the set of all values greater than or equal to 0 and less than or equal to 2. WebJul 20, 2024 · With interval notation, we write the leftmost number of the set, followed by a comma, and then the rightmost number of the set.
