ok so i got (5+cos x)/e(adsbygoogle = window.adsbygoogle || []).push({}); ^{x}and i compared that with 1/e^{x}

(they're both going from 0 to infinity).

Turns out that the integral of 1/e^{x}from 0 to infinity converges to 1. But i don't know how to prove that our original function converges as well (which is the answer). Anyone care to help?
