At one point during the day some forward-thinking bacteria get the idea that they are facing a crisis. their numbers are growing exponentially and they are using up their space and food at an ever increasing rate. at what time do you think the idea would come?

Horizontal asymptote at  tells us that the original graph has been translated down.since  ,  are positive.  also we can say that the point  has a smaller  -coordinate than  .this means that the  transformed exponential function is increasing as it goes to the right. as it goes from  to , the value of the exponential function increases. it goes from to something bigger, . therefore, as  . the left hand would be the side that approaches the horizontal asymptote.so the answer is d
