LG 3: Compositions and Inverses of Functions

UNIT 8 - Relations/Functions/Graphs


Learning Objective:   BTEOTPSWBAT......
  • evaulate composition of functions in general, or at a given value
  • show that two functions are inverses using composition
  • find the inverse of a given function or a set of ordered pairs.

COMPOSITION OF FUNCTIONS

NOTES VIDEO 1: 
Hint:( If it doesn't make sense, you may need to watch it twice. The sub may or may not be able to help.)

2. Go pick up a "composite functions" worksheet and watch this video about the "composite functions" w/s. 
The answer key is in the front of the room for this practice.





INVERSES



        - What is an inverse?
        - how do you find one from an equation?
        - What happens when you compose one                       function with its inverse?
