Function Notation
Pronunciation: /ˈfʌŋk.ʃən noʊˈteɪ.ʃən/ Explain
 Figure 1: Function notation diagram 

Function notation is a way to write
functions
that clarifies the name of the function, the
independent variables,
the
dependent variables,
and the transformation rule.
In the example on the right, f(x)
is the dependent variable, f is the function name, x is
the independent variable, and 3x + 2 is
the transformation rule.
