Final answer:
A functional region is created by the interaction and connection between different locations that serve a specific purpose. Examples include a public transportation system, the broadcast area of a local television station, suburbs around a city center, and the customer base of a particular business.
Step-by-step explanation:
A functional region is a region that is defined by a practical function within a given area. It is created by the interaction and connection between different locations that serve a specific purpose. Examples of functional regions include a public transportation system, the broadcast area of a local television station, suburbs around a city center, and the customer base of a particular business. The influence of an elected official, on the other hand, is not a factor that creates a functional region. It is more related to political boundaries and representation.
