The number of bacteria in a sample increased by a factor of 2 every minute from 9:05 AM to 9:55 a.m.. The function below shows the number of bacteria in the sample f(x) after x minutes from 9:05 a.m.: f(x) = 10(2)x Which of the following is a reasonable domain for the function?

A0 ≤ x ≤ 10

B5 ≤ x ≤ 55

C0 ≤ x ≤ 50

DAll positive integers

Verified Answer :

apologiabiology

thinking that the equation is \(f(x)=10(2^{x})\)
obvously, you cannot have negative numbers
thinking the domain is the experimented set
find how long

9:05 to 9:55 is 50 mins

would guess C
also D is possible

the answer is C. \(0\leq x\leq 55\)
