Answer

The average value of f(x)=x2+x8 on [0,16] is 2563.

Steps

Step 1 :The average value of a function f(x) over the interval [a,b] is given by the formula: 1baabf(x)dx

Step 2 :In this case, f(x)=x2+x8, a=0, and b=16. So we need to calculate the integral of f(x) from 0 to 16, and then divide by 160=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+x8 on [0,16] is 2563.
