Answer:
Functions of Concepts are :
1) A mental shorthand into our memory = we can fit so much information in this single entity
2) Predicting = Because we have concepts of things and know how things tend to play out, we can predict certain things, like when we have a test, we know we need a pen and paper, etc.
3) Learning = We are able to learn new things by matching new information to concepts we already have
4) Communication = Because of concepts, we can represent them into words (represent entire concepts)
