Answer:
C. The total number of bacteria present in the sample after 2 hours is 12.
Step-by-step explanation:
If f(x) is the total number of bacteria present in a sample and x is the number of hours, then the meaning of f(2) = 12 is that the number of bacteria present in the sample is 12 after 2 hours.
When you replace the x for 2, it ends up in f(2), that’s the number of bacteria in the sample after 2 hours, then the function says that f(2) =12, therefore the number of bacteria after 2 hours is 12.
