Answer:
Yes, but it is not linear. It is exponential : [tex]f(x) = 5\cdot 2^{x-1}[/tex]
Step-by-step explanation:
On the first day we have 5 bacteria.
On the second day we will have 5*2 = 10 bacteria.
On the third day we will have 10*2 = 5*2*2 = 5*2^2 = 20 bacteria.
On the fourth day we will have 20*2 = 5*2*2*2 = 5*2^3 = 40 bacteria.
We can see that
[tex]f(x) = 5\cdot 2^{x-1}[/tex],
where x is a number of days and f(x) gives us the number of bacteria.
