Find the limit as x approaches negative infinity of 8/(e^x - 5)

OpenStudy (anonymous):

Why is the answer not infinity?

OpenStudy (luigi0210):

Did you plug in -infinity?

OpenStudy (anonymous):

Yep, e gets closer to zero, so, 1/0 is infinity.

OpenStudy (luigi0210):

You do know e^(infinity) = A really really really really really REALLY big number, right?

OpenStudy (anonymous):

Silly mistake, I was thinking the 8 and -5 would not make a difference, then I realized I was being stupid.

OpenStudy (luigi0210):

So understand why it's 0 now? xD

OpenStudy (anonymous):

Limit is 8/-5, as e^x would be zero, so, you're left with 8/-5

OpenStudy (luigi0210):

Actually, e^infinity =infinity >_>

OpenStudy (luigi0210):

@Loser66 how am I doing? xD

OpenStudy (loser66):

don't forget e^x is at denominator!!!

OpenStudy (luigi0210):

I was getting there :P @frostyjesus make sense or no?

OpenStudy (luigi0210):

Crap, nvm, he was right it was 0 >_>
