Which of the following tools make use of the DAX programming language? (Select all that apply.)
DAX (Data Analysis Expressions) is the formula language used for creating measures, calculated columns, calculated tables, and row-level security expressions in tabular data models. According to Microsoft's official documentation, DAX is used in Power BI (Power BI Desktop and Power BI service), Power Pivot in Excel, and Analysis Services (Tabular models). Tableau does not use DAX — it relies on its own calculation language and VizQL engine, so it is not among the tools that use DAX.
