The Average Rate Of Change is our first attempt at looking at
functions in a dynamical way. Instead of plugging in values for the input variable and obtaining static
information about function values ( such as if f(x)=3x+5, then f(4)=3*4+5=17), we will be able to give
additional information about the behaviour of the function. The Average Rate of Change is still a
rather primitive tool to get dynamical information, and we will soon introduce a more sophisticated
measure: the Instantaneous Rate of Change.
The Average Rate of Change is represented in mathematics by the notation
