so you would just plug (6) in for your t here

$$f(6) = 1,170,000(1.12)^6$$

Agreed...

btw, the formula is just saying that each year, the population is expected to be about 12% larger than it was in the previous year.  multiplying by 1.12 adds 12% each time.  It is sobering to look at how few years it will take to double the population if it is growing at a 12% rate!
