**Could There Be 2 or even more Break Even Points?**

The main article considers the simplest case, when the function TC (total cost) grows linearly (y=ax+b).

But we can image a different non-linear mathematical law describing the costs (y=ax^2+c or y=lnx +c).

Probably in this situation there are two or even more break event points. Then the visible levels (in the calculation) maximum profit may not be optimum.

So remember yes: there can be investment situations with 2 or even multiple break-even points!
