### LG 3: Compositions and Inverses of Functions

 UNIT 8 - Relations/Functions/GraphsLearning Objective:   BTEOTPSWBAT......evaulate composition of functions in general, or at a given valueshow that two functions are inverses using compositionfind the inverse of a given function or a set of ordered pairs.COMPOSITION OF FUNCTIONSNOTES 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.INVERSESNotes video 1: What is an inverse/finding an inverse - eduPortal        - What is an inverse?        - how do you find one from an equation?        - What happens when you compose one                       function with its inverse?Practice 1: Find the inverse - Khan AcadPractice 2: Evaluate Compositions - KhanAcad                       EXTRA PRACTICE Penn State Module2 - compositionsEvaluate Composite Functions - KhanAcad Inverses from graphs- KhanAcad
