A park ranger uses exponential functions to model the population of two species of butterflies in a state park.
The population of species A, x years from today, is modeled by function f.
f(x) = 1,400(0.70)x
The population of species B is modeled by function g, which has an initial value of 1,600 and increases by 20% per year.
Which statement correctly compares the functions modeling the two species?
A.
The population of species A is decreasing, and it had the greater initial population.
B.
The populations of both species are increasing, but the population of species B is growing at a faster rate than species A.
C.
The population of species A is decreasing, and it had the smaller initial population.
D.
The populations of both species are increasing, but the population of species A is growing at a faster rate than species B.
