Welcome to the Graphs of Life

Who is this guy? He is seventeenth century french mathematician and philosopher Rene Descartes. He changed the way we think about the world around us. Have you heard his name in history class? If you haven't, you probably will - he is famous for the philosophical movement of skepticism which involves believing only that which you can deduce through logic. He also invented the Cartesian Coordinate System of graphing that we use today. Without it, scientists would be helpless to explain their findings to the world. Businesses would not be able to describe what is happening to their products. The world would be a lot more difficult without this useful mathematical tool and, more importantly, X's and Y's would be forced to roam the streets without a purpose in life. But these X's and Y's are useful fellows, and you'll soon see that they can be useful for you. They communicated trends in the world - everything from how fast a substance heats up to population changes to the changes in your own daily activities, the makeup of your life. Let us navigate through the dimension of graphing to better understand our world. Let us become masters of all that can be accomplished with graphs through exploring useful graphs in the outside world and creating graphs of our own lives.
Review of Graphing Points and Relations of Graphs
Unit 1: Graphing Functions
How are functions related to graphs? How can they help us to describe graphs we see in the real world or create?
Unit 2: Identifying Graphs
What types of graphs appear in the real world? What are the features of these graphs?
Unit 3: Analyzing Graphs of Own Creation
If you were to graph something for your own life, what type of graph would it resemble?
