Unit 5: Relations and Functions
Researchers use graphs in virtually every area of science and math. We can often gain more insight by studying the graph of an event than by studying the event itself. Solutions to questions that become lost in volumes of data can become quiet clear when the data are plotted on a graph. For example, in driver’s education, you learn about the appropriate "safe" distance you need to stay behind other vehicles so there is enough time to stop. Below is a chart that displays your speed, thinking distance (how far the car travels from the time you decide to brake until you actually brake), braking distance (how far the car travels until it stops) and the total stopping distance. I think you will agree that it is much easier to see and interpret the data in a graph than in a table. Upon completion of the activities in this unit, you should be able to:
