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? a \small f\left(d\right)=10,000\cdot2^d b \small f\left(d\right)=10,000\cdot\left(\s qrt[5]{2}\right)^d c \small f\left(d\right)=10,000\cdot\left(\f rac{1}{\sqrt[5]{2}}\right)^d d \small f\left(d\right)=10,000\cdot2^{5d}
