This math topic focuses on converting interval notation into set builder notation, specifically relating to the domain and range of functions. Students practice identifying and describing intervals, such as open, closed, or semi-open intervals, and then translating these descriptions into the correct form of set builder notation, without using union. This involves understanding and using mathematical symbols and the concept of where variables such as \(X\) and \(Y\) lie within the real numbers (\(\mathbb{R}\)). Each question asks to describe either a domain or range from provided interval notations.
