Question

The population of a certain bacteria colony can be modeled by the function f ( x ) = 2 x , where x is the number of hours after the colony started. What will the population of the bacteria colony be after 12 hours?

Answer 1

The answer is 24

Explanation:

Since the population after x hours is 2x, then after 12 hours, we'll substitute x = 12 into the function.

The population becomes 2 x 12 = 24
