Functions

Discovery lesson for learning about function vocabulary and functions/non functions- uses power point shown below....

[|Function Machine]- Cute visual of input/output for exploring linear functions.

[|Number Plumber]- program for exploring input/output of linear functions- includes table and graph...

Powerpoint for "discovering functions". Explores what functions look like in a table and graph. - short powerpoint attempting to show relationship between patterns, functions, and graph of functions. Practice evaluating functions for given values.

Information about the origin of the "Turducken". A friend of mine shared this as a great motivator for evaluating composite functions. (a turducken is a deboned chicken stuffed in a deboned duck stuffed in a deboned turkey and roasted)

Worksheet of composite function examples for students to complete.

I cut these into strips and share them one at a time. Students work in pairs to create a graph that meets the restrictions. Then I have a student come up and share their graph, and another student come up to the screen and check the restrictions to make sure that the graph works. Usually I have 2-3 students share for each graph- more with those that allow for many different possible graphs.

More examples of graphing a function with a set of rules/restrictions- sometimes homework after the "creating functions" classwork described above. - Quadratic functions for students to use to determine zeroes and maximum/minimum on the graphing calculator.
