This topic focuses on interpreting inequalities in the context of defining the domain and range of functions. The math skills practiced include translating inequalities represented symbolically into verbal descriptions of domains and ranges of functions. Questions involve determining whether inequality descriptions include boundaries (such as "greater than or equal to" vs. "greater than") for real number sets defined by inequalities without unions, such as "3 ≤ Y ≤ 6" and "-2 < X". The emphasis is on understanding and accurately describing open and closed intervals within the real number system.
