This math topic focuses on interpreting mathematical intervals and converting them into descriptive statements about domains and ranges of functions. It includes understanding both open and closed intervals and expressing them in words, specifically targeting relations like "greater than," "less than," "greater than or equal to," and "less than or equal to." The problems do not use union operations and vary between asking about domain and range, enhancing fundamental comprehension of how intervals are used to describe these function properties.
