Find the average value over the given interval.f(x)=x2+x−8;[0,16]The average value of f(x)=x2+x−8 on [0,16] is (Type an integer or a simplified fraction.)
The average value of f(x)=x2+x−8 on [0,16] is 2563.
Step 1 :The average value of a function f(x) over the interval [a,b] is given by the formula: 1b−a∫abf(x)dx
Step 2 :In this case, f(x)=x2+x−8, a=0, and b=16. So we need to calculate the integral of f(x) from 0 to 16, and then divide by 16−0=16.
Step 3 :Calculate the integral of f(x) from 0 to 16.
Step 4 :Divide the result by 16 to get the average value.
Step 5 :The average value of f(x)=x2+x−8 on [0,16] is 2563.
