Explicación
## Step 1The given function is \(f(x) = 5,200(1.1)^x\). This is an exponential function, which is generally represented in the form \(f(x) = ab^x\), where
is the initial amount,
is the growth factor, and
is the time.## Step 2In the given function, 5,200 is the coefficient of the exponential term. In the context of the problem, this represents the initial population of cottontail rabbits in Orange County. This is because when
(i.e., at the beginning), the function simplifies to \(f(0) = 5,200(1.1)^0 = 5,200\). This means that the initial population of rabbits is 5,200.## Step 3The base of the exponential term, 1.1, is the growth factor. This means that each year, the rabbit population grows by a factor of 1.1. This is because when
(i.e., after one year), the function simplifies to \(f(1) = 5,200(1.1)^1 = 5,720\). This means that the rabbit population increases by 10% each year.
