Question

In 2011 Texas population was 2145000 an increase of 2.2% compared to the previous year. 1. Assuming that the population continues to grow 2.2% a year write the equation of a function f(x) that can be used to model the population in millions, where x is the number of years since 2011

Answer 1

okay so we started with a pop. at 2145000 and every year it increased by 2.2%

year 0= 2145000
year 1= 2145000 (1+.022)
year 2 = 2145000 (1+.022)(1+.022)
year 3 ????

Answer 2

what would the equation look like?

Answer 3

2145000(1.022)^t

Answer 4

so then 2145000(1.022)^3

Answer 5

you got the formula isnt that what you need?

Answer 6

yeah thanks
