http://tinypic.com/view.php?pic=1xa2f&s=5 (this shows the graph that is related to the problem)

is the graph of an anti-derivative, F, of a

function f, use this graph to determine the value of I=∫ from 0 to 8 |f(x)|dx.

value of the deﬁnite integral

2. Relevant equations

3. The attempt at a solution

The answer choices are 11, 12, 13, 14, or 15. I have no idea how to get these answers. I looked at the graph and used Reimann Sum technique of counting up the squares, but I get numbers in the 20's. For absolute value functions, I know you switch any negative values to positive, but this whole function looks positive to me? Thoughts?
