Introduction to Relations and Functions

Learning Target for this Lesson: I can explain what a function is. I can explain what a relation is. I can determine if a relationship is or is not a function. To do this, I  must know how to analyze tables, graphs, and coordinates. I must understand the difference between a function and a relation, and the difference between domain and range. I will show my understanding by determining whether or not a function is presented.

Students should be able to complete this Webquest within a 50 minute class period. Because it shouldn't take the students that long to complete, I suggest you take a look at the conclusion page and see what I have assigned the students after they have turned in their answer sheet for the webquest.
