okay the problem asks to integrate this function from 0-infinity(adsbygoogle = window.adsbygoogle || []).push({});

i integrated but the answer i get is e^-lambdax from 0 to infinity

so e^0 is 1

and you will have 1-e^-lambda(x) where x is infinity

how does this come out to be -1?

please explain to me...i think i just forgot a rule
