A population of deer mice lives in a neighborhood. Which of these changes to the neighborhood could increase the carrying capacity of this population?

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

Answer is 39
You just either add 13 three times or add 3 thirteen times.
