Question
Find the average value fave of the function f on the given interval.f(x) = x, [0, 16]
Solution
The average value of a function, f(x), over the interval [a, b] is given by the formula:
fave = (1/(b-a)) * ∫ from a to b of f(x) dx
Here, our function f(x) = x and the interval is [0, 16]. So, a = 0 and b = 16.
Let's calculate the integral first:
∫ from 0 to 16 of x dx = [0.5x^2] from 0 to 16 = 0.516^2 - 0.5*0^2 = 128.
Now, we can find the average value:
fave = (1/(16-0)) * 128 = 8.
So, the average value of the function f(x) = x on the interval [0, 16] is 8.
