The integral of f(x) from a to b = F(b) - F(a)
|x| = { x if x >= 0; -x if x < 0

Ok, I don't know how to do the definite integrals of absolute values.. was never shown an example of it in class, but I kind of have an idea...
we know that
|x| = { x if x >= 0; -x if x < 0,
and then I am lost from here...
btw, x= 1, -2
