Question

There is a population of 5 bacteria in a colony. If the number of bacteria doubles every minute, which function can be used to determine what the population will be x minutes from now?

Answer 1

Answer:

$f(x) = 5 *2^x$

Step-by-step explanation:

Given

$a=5$ -- initial

$r = 2$ --- rate (i.e. double)

Required

The function to represent the scenario

The above scenario represents an exponential function where

$f(x) = ar^x$

So, the function is:

$f(x) = 5 *2^x$
