Interpreting Exponential Functions Using Function Notation Task

The number of people with the flu during an epidemic is a function, f, of the number of days, d, since the epidemic began. The equation f(d) = 50·(3/2)d defines f. How many people had the flu at the beginning of the epidemic? Explain how you know.
