Step-by-step explanation:

The exponential growth or decay function is a function that grows or shrinks at a constant percent growth rate. The equation can be written in the following form:


f(x)=a(1+r)^x

or


f(x)=ab^x\text{ where b= 1+r}

here

a is the initial or starting value of the function or initial population.

r is the percent growth or decay rate, written as a decimal

and

b is the growth factor or growth multiplier.

Now, consider the following exponential model:


f(t)=523\left(1.099\right)^t

notice that in this case:

a = 523

according to the definition of exponential growth, we can conclude that the correct answer is:

Answer:

523 is the initial population of deers.
