Ginny is studying a population of frogs. she determines that the population is decreasing at an average rate of 3% per year. when she began her study, the frog population was estimated at 1,200. choose the function that represents the frog population after x years.

a. f(x) = 1,200(1.03)x
b. f(x) = 1,200(0.03)x
c. f(x) = 1,200(0.97)x
d. f(x) = 1,200(0.97)x

Step-by-step explanation:

The exponential decay equation is given by :-

, where A is the initial amount, r is the rate of decay in x years.

Given: The rate of decreasing of the population of frog = 3% =0.03

The population of frog at the beginning i.e. Initial population =1,200

Hence, the  function that represents the frog population after x years.

is given by :
