Hi Math-folks,

I am now thinking about this for a few days but I cannot find a solution to it. Would be nice if you could help me.

I just want to write a problem exression to a linear one (see attachments).

B(x) can be an area or volume. It is the neighborhod of f(y). (where delta is the size of the neighborhod)

The idea behind the function is to average the value of f(y).

Would be a big help! Thanks!
