In the second half of Unit 2B, we focus on function operations. Aside from the notation, this is a review of polynomial operations. We add on function compositions (evaluate functions at other functions), and inverses of functions (finding and verifying inverses).

Function Compositions

Function Compositions Notes/ Function Compositions Practice: Practice is on the last slide of the notes PowerPoint.

*Follow the video for adding, subtracting, and multiplying functions. In addition to the method shown in the video for multiplying, you can also use the BOX METHOD. We will not be dividing the way they do in the video. See me for information on how to divide.

Day 2: Around the Room Practice: See me in class to get copies of the in the hall practice.

Function Inverses -2/28/22

In addition to finding the inverse of functions we will be verifying inverses f(g(x))=x and g(f(x))=x.
