Average Rate of Change
  
      
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  

      
The Average Rate of Change is defined as the change in the function value, divided by the change in the corresponding input variable's values. Therefore:
