Learn how the Mean Value Theorem for Definite Integrals guarantees an average value equal to the actual value of a continuous function. Explore examples with f(x) = x^2 and f(x) = sin(x).

Mean Value Theorem 4.4b
Mean Value Theorem (for definite integrals) If f is continuous on then at some point c in , The mean value theorem for definite integrals says that for a continuous function, at some point on the interval the actual value will equal the average value. p
The average value of a function is the value that would give the same area if the function was a constant:
Example • Find the average value and the “c” guaranteed by the MVTI of f(x) = x2 on the interval [2, 4]
Example • Find the average value of f(x) = sin x
