Summary: Function Notation

Function Notation-                                                                             August 18, 2011

OBJECTIVE: SWBAT DEFINE, EXPAND, AND CREATE RELATIONS THAT ARE FUNCTIONS AND NOT FUNCTIONS

Today we learned about function notation and how to use it. Function notation is f(x)=y and is read as "f of x". For example, y=2x+1 can also be written as f(x)=2x+1. Examples of how to solve problems for function notation is shown below. The domain cannot contain values for which the range is undefined (0).

EXAMPLE:

f(x)=4x²-2x+5              f(4)                       
     =4(4)²-2(4)+5
     =4(16)-2(4)+5
     =64-8+5
     =56+5
     =61
