Can someone please explain how to find the average value of a function
Say I have f(x)=X^2+2 on [1,4]. I think I have to to 1/b-a, but that is about all I know to do.
1/(a-b) * integral of F , bounds a to b. It's a simple concept really. You have the total area of a region. If you make a rectangle from a to b with the same area, but one height obviously, the way to find this height is to divide the area by the width.
