This caused issues in the global supply chain, slowing and even halting economic processes in the US as large freighters with goods bound for the US were not leaving ports in Asia. What specifically are geographers examining when they study this issue?

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
