## Homework Statement

## Homework Equations

delta x = (b-a)/n

## The Attempt at a Solution

Well, from the delta x formula I can figure out the limits of integration. They're 4 and 0. That leaves us with three possible answer choices. I'm suspecting that the 4i/n term goes away and the answer is B, but I really don't know and I'm not even sure where to begin.
