Final answer:
An instrumental leader is goal-oriented and focused on accomplishing tasks, while an expressive leader is more concerned with emotional well-being and support. Examples include army generals, Fortune 500 CEOs, and social/religious leaders.
Step-by-step explanation:
Leadership function refers to the main focus or goal of the leader, which may be instrumental or expressive. An instrumental leader is one who is goal-oriented and largely concerned with accomplishing set tasks. An example of an instrumental leader would be an army general or a Fortune 500 CEO. In contrast, expressive leaders are more concerned with promoting emotional strength and health, and ensuring that people feel supported. Examples of expressive leaders may include social and religious leaders, such as rabbis, priests, imams, or directors of youth homes and social service programs.
