Explanation:
The formula for average value of f(x) from x=a to x=b is the integral of f(x) from a to b, divided by (b - a). b - a is the length of the interval over which you are finding an average value. In order to calculate the average value, simply plug in values of a, b, and f(x) into the formula.
