Which of the following parameters can be stored in a formula-type parameter?

A formula-type parameter in Salesforce is designed to evaluate and return a specific result based on the expression defined within the formula. The capability of formula-type parameters to handle multiple data types is key to their functionality.

Text, number, and date values can all be incorporated within a formula-type parameter, allowing for versatile calculations and evaluations that can utilize both numeric computations and date manipulations, alongside string processing. For example, you could create a formula that calculates a percentage (a numeric value), evaluates if a date falls within a certain range, or concatenates two text fields together. This flexibility is crucial for meeting the diverse needs of various organizational use cases.

In contrast, focusing solely on any one specific type of value, such as only date values, Boolean values, or any SObject type, would restrict the utility of the formula-type parameter. The design is aimed at enabling the combination of various data types to enhance the business logic that can be implemented within Salesforce, making them far more powerful and beneficial than being limited to just one type of data.
