What are the three primary functions of the Formula tool?

The three primary functions of the Formula tool in Alteryx are to create and manipulate expressions within the workflow. This allows users to create new fields based on calculations or transformations of existing fields. By building an expression, users can define how data should be processed or modified. Adding an additional expression allows for the incorporation of more complex logic or operations, while reordering expressions enables the adjustment of calculation priorities, enhancing flexibility in data transformations.

In this context, the other options do not accurately capture the main functionalities of the Formula tool. The construction and management of input data and visualization of results, mentioned in other choices, are not direct operations performed by the Formula tool itself, but rather pertain to other tools and functionalities within Alteryx. Additionally, actions like deleting or assigning data types are not considered primary functions of the Formula tool; instead, the focus is on crafting expressions to alter data.
