PLEASE HELP FAST AND GIVE ME A PARAGRAPH Lin counts 5 bacteria under a microscope. She counts them again each day for four days, and finds that the number of bacteria doubled each day—from 5 to 10, then from 10 to 20, and so on.

is the population of bacteria a function of the number of days? Explain your reasoning.

Yes, but it is not linear. It is exponential  

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 where x is a number of days and f(x) gives us the number of bacteria.

i use my brain for prombles like this maybe you could try it
