The population of bacteria can be expressed as a function of number of days.
Population =![\[5*2^{n-1}\]](/tpl/images/0521/3210/86c78.png)
where n is the number of days since the beginning.
Step-by-step explanation:
Number of bacteria on the first day=![\[5 * 2^{0} = 5\]](/tpl/images/0521/3210/76b0b.png)
Number of bacteria on the second day =![\[5 * 2^{1} = 10\]](/tpl/images/0521/3210/c504e.png)
Number of bacteria on the third day =![\[5*2^{2} = 20\]](/tpl/images/0521/3210/1bac1.png)
Number of bacteria on the fourth day =![\[5*2^{3} = 40\]](/tpl/images/0521/3210/c8eb6.png)
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![\[5*2^{n-1}\]](/tpl/images/0521/3210/86c78.png)
where n is the number of days since the beginning.
