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. [math] f(x) = 7,400,000 (1 + .054)^x [/math]
  2. [math] f(x) = 7,400,000 (1 - .054)^x [/math]
  3. [math] f(x) = 7,400,000 (.054)^x [/math]
  4. [math] f(x) = 7,400,000x^(.054) [/math]
