After years of maintaining a steady population of 32,000 , the population of a town begins to grow exponentially. After 1 year and an increase of \( 8 \% \) per year, the population is 34,560 . Which equation can be used to predict, \( y \), the number of people living in the town after \( x \) years? (Round population values to the nearest whole number.) \( y=32,000(1.08)^{x} \) \( y=32,000(0.08)^{x} \) \( y=34,560(1.08)^{x} \) \( y=34,560(0.08)^{x} \)

Did you know that exponential growth can be observed in many natural and social phenomena? When a population increases at a constant rate, like the 8% increase here, it often leads to a surprisingly fast growth over time, similar to how investments can grow with compound interest. The formula you're looking for, \( y=32,000(1.08)^{x} \), effectively captures this dynamic—showing how a modest initial population can balloon dramatically! Speaking of mistakes, one common error is confusing the growth factor with the rate. Remember, \( 1.08 \) accommodates for the original whole (100% of the population), along with the additional 8%. If you mistakenly just used \( 0.08 \), you'd be only considering the growth, leaving out the existing population—fatal for those predictive models!
