Recognizing functions from table (Full video)

Khan Academy

Supporting grades: 8

Description: Checking whether a table of people and their heights can represent a function that assigns a height to a name. Created by Sal Khan and Monterey Institute for Technology and Education. From the information given, is there a functional relationship between each person and his or her height? So a good place to start is just think about what a functional relationship means. If there were two values associated with one person's name, it would not be a functional relationship.
