Question

suppose a population of 250 fleas doubles in size every month. The function f(x)=250(2^x) gives the population after x months. How many fleas will there be after 1 year?

Answer 1

f(x) = 250(2^x)
f(12) = 250 (2^12)
Calculate f(12) = 250 (2^12) and you should have the answer. Just remember that f(12) stays the same since it is a function.
