EASY Find the Average Value of f(x) (Calculus Tutorial)

In this calculus tutorial we will find the mean value or the average value of any function f(x) on a closed interval from a to b. This is a common problem in calculus class and we will make it easy.
Understand that the mean value is the sum of individual values divided by the number of of values. Using this we can say that the mean value c of a function f(x) from x = a to x = b is equal to the integral of f(x) dx from a to b divided by b - a. Using this we can also say that the mean value c multiplied by b-a is equal to the integral of f(x) from a to b.
