Ch 1 Real World Functions

By Ellie Cosine (team cosine)

For our real world function we did Disney movies and when they were made. The domain are the movies and the range are when the movies are made. For this to be a function only one year can match with one movie. If there were two movies for one year then it would fail as a function. Our independent variable are the movies and our dependent variable are when they were made. Our graph will not be a function when you add put a random year to one of the movies. For example, putting a random year to Toy Story 3 will make it a relation.
