Step-by-step explanation:

The given statement :  f(x) is the total number of bacteria present in a sample after x hours.

It means the independent quantity = Number of hours

i.e. The independent variable in the given situation = x

Also, the dependent quantity =  Total number of bacteria

i.e. The dependent variable in the given situation = f(x)

Therefore, the meaning of "f(2)=12" is the total number of bacteris present in sample is 12 after 2 hours.
