(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I'm having trouble understanding this pair of claims:

2. Relevant equations

3. The attempt at a solution

So g is some function whose result is greater or equal to 0... but I don't really get what the rest of the claim means.

Could someone please explain them to me?

Thanks in advance.
