Consider f(x)=2|x| What is the rate of change over the interval 0≤x≤4?

How is the rate of change over this interval related to the form of the function?

Please check the explanation.

Step-by-step explanation:

As we know that the average rate of change of f(x) in the closed

interval [a, b] is

Given the interval [a, b] = [0, 4]

as

      ∵  

      ∵  

so the average rate of change  :

We know that a rate of change basically indicates how an output quantity changes relative to the change in the input quantity. Here, it is clear the value of y increase with the increase of input.
