Scientists measure a bacteria population and find that it is 10,000. Five days later, they find that the population has doubled. Which function f could describe the bacteria population d days after the scientists first measured it, assuming it grows exponentially?
f(d) = 10,000 x 2^d
f(d) = 10,000 x (^5/2)^d
f(d) = 10,000 x (1/^5/2)^d
f(d)= 10,000 x 2^5d
