FunctionThe relationshipbetween the inputand output values
FunctionEach input value has   EXACTLY one    output value
FunctionFunction Notation:f(n) = n + 5Output   Input
FunctionFunction Notation:f(n) = n + 5      Rule for Function
Function     Example:You are driving a car  50 miles per hour        (mph)
Function  Example:   D=rt   d = 50t  d=distanceR= rate t=time
Function Set up a table using the previous      function rule: d = 50 t  Time     1   2     3     4     5 (Input)Distance(...

AnswerDefine the variable     s = salary     h = hours Function Rule  s = 6.50 h
FunctionFind the Rule ~ then look at next    slide to see if you are correct        Weeks         Plant Height          1 ...
