Example 3

Raven is meeting with investors that are interested in investing in her online social media website, which is set to launch soon. On the first day the site is launched, she will start with 32 subscribers. Raven is predicting that the number of subscribers will double every day. Raven’s prediction can be modeled by the exponential function f(x) = 32(2)x. Evaluate f(3) and interpret the results in terms of this prediction.
