Step-by-step explanation:
Key Functions of DFC and Money
The student is inquiring about different sets of functions, one related to DFC (Dynamic Functional Connectivity) and another to the functions of money. As the context is not fully clear for DFC, let's focus on the well-known four functions that money serves which are:
- Medium of exchange
- Unit of account
- Store of value
- Standard of deferred payment
These functions are essential to the economy, as money simplifies transactions by eliminating the need for a double-coincidence of wants. Instead of finding someone who has what you want and wants what you have, money provides a common ground for value. For example, it allows people to compare the value of different goods and services.
In a different context, the concept of DFC in fields like neuroscience refers to variable connections between different brain regions and how they change dynamically. However, the specific functions of DFC are not provided here.
If the question was referring to functions of government according to functionalism, then these would be: planning and directing society, meeting social needs, maintaining law and order, and managing international relations.
