At your level, i would say that

The non integrable functions are those for which the integral by the first principle does not exist (Do you remember the integral as the sum>?)

There is a formal definition and there are 2-3 ways in which an integral can be defined.. but at this stage that is something that is not going to help your cause at all.

Like dont confuse that e-x2 is non integrable. It is integrable but the integral cannot be expressed in a "nice form"
