The population of bacteria can be expressed as a function of number of days.

Population = where n is the number of days since the beginning.

Step-by-step explanation:

Number of bacteria on the first day=

Number of bacteria on the second day =

Number of bacteria on the third day =

Number of bacteria on the fourth day =

As we can see , the number of bacteria on any given day is a function of the number of days n.

This expression can be expressed generally as where n is the number of days since the beginning.
