Ch 4.4 – The Fundamental Theorem of Calculus (day 2) Target Goals: Find the value of c guaranteed by the Mean Value Theorem for Integrals Find the average value of the function over an interval.
Mean Value Theorem for Integrals • If f is continuous on [a, b], then there exists a number c in the interval [a, b] such that:
Average Value of a Function • The value of f (c) given by the MVT for integrals is the average value of f on [a, b]. • If f is integrable on [a, b], then the average value of f on the interval is:
Example 1 • Find the value of c guaranteed by the MVT for integrals:
Visual Representation of Average Value of a Function and MVT • http://archives.math.utk.edu/visual.calculus/5/average.1/ • The area of the region under the graph of f is equal to the area of the rectangle whose height is the average value.
Example 2 • Find the average value and all values of x in the interval for which the function equals its average value. Average value
