Now what should I look up to understand a question like this one:(adsbygoogle = window.adsbygoogle || []).push({});

Function h is decreasing on the interval [4,infinity) and lim h(x)(with x approaching infinity)=8, what would be the limit g'(x)(with x approaching infinity)?

I don't nessicarily need the answer, but could someone point me in the right direction?
