Suppose it takes the population of a certain strain of bacteria 1 day to double in size. If the initial population is 100 cells, the population of bacteria can be computed days afterward by using the function .f(x)=100*2^x
Use the graph to answer the questions.
What is the population after 7 days? 
 cells
When will the population first exceed 60000 cells? 
 days (round down to the nearest tenth of a day)
