Question

The population of a city is 451,400. The population is expected to decrease at a rate of 3.2% each year. Which function equation represents the population of the city after t years?

A. f(t)=451,400(1.032)t
B. f(t)=451,400(3.2)t
C. f(t)=451,400(0.968)t

Answer 1

The correct function equation representing the population of the city after t years with a decrease rate of 3.2% each year is:

C. \( f(t) = 451,400(0.968)^t \)
