PreCalculus Power Functions Unit 2

Now that we've established all the characteristics of functions and various processes used on functions we can now analyze some different function types.

Unit 2 is all about power functions. We cover this initially in a general way, then focus on polynomial functions and rational functions. We don't review quadratics. They saw those plenty in Algebra 1 & 2.

The start of this unit begins right after the unit 1 test. Students have an exploration of power functions to complete for homework after the test.

Students share their generalizations on my whiteboards. Then we fill in our ISN foldable on power functions.

We support this ISN foldable with our "right hand reflect" page being about "Power Function Facts".


And finish off by looking at power regression. We use the TI graphing calculators in class. I give students a instructions sheet that I use in Algebra One. But I remind them that we are looking at power function regression in this class, not linear regression. Finally we do an example with antelope data.
