yeah i know they make energy but what is it used for in the small intestine? active transport at all? or is all food absorbed by diffusion?

Yes, it has to do with active transport of nutrients. Active transport is one of the major mechanisms of absorption of subtances like glucose, amino acids etc..
This needs lots of energy to do, so the Mitochondria are the powerhouses that make ATP for these jobs.

Mitochondria perform the same function in every cell in your body: making ATP. In your intestines, nutrients are absorbed by villi and micro villi. Those nutrients are transported throughout your body...including to the mitochondria in the cells that make up your small intestine. The mitochondria themselves play no role in absorption (except to provide the cell with energy to stay alive).

the same thing they do anywhere else: produce atp (anedosine triphosphate) to be used as energy by breaking the bonds between one of the 3 phosphate groups

mitochondria will always just make ATP the cells, so they can preform their functions
