In the year 2000, the population of Virginia was about 7,400,000.
Between the years 2000 and 2004, the population in Virginia grew
at a rate of 5.4%. At this growth rate, what function gives the population x years after 2000.
1. $f(x) = 7,400,000 (1 + .054)^x$
2. $f(x) = 7,400,000 (1 - .054)^x$
3. $f(x) = 7,400,000 (.054)^x$
