The number of fish, \(f\), in Skipper's Pond at the beginning of each year can be modeled by the equation \(f(x)=3(2^x)\), where \(x\) represents the number of years after the beginning of the year 2000. For example, \(x=1\) represents the beginning of the year 2000, \(x=1\) represents the beginning of the year 2001, and so forth. According to the model, how many fish were in Skipper's Pond at the beginning of the year 2006?
