Question

The average value of g(t) over the interval [0,3] is given by
A. (g(3) +g(0))/2.
B. (g(3)−g(0))/3.
C.1/3∫[3,0]g(t)dt.
D. 3∫[3,0]g(t)dt.
E. None of the above

Answer 1

You know the area under the curve is ∫[3,0]g(t) dt
You want the height of a rectangle with the same area.
So divide the area by the width, and you get choice B

Answer 2

Thanks for your help!

Answer 3

That is actually C I think.
