Rabbits in a colony breed and give birth to baby rabbits. What model best describes the total number of rabbits in the colony ov
zimovet [89]

Answer: A) Exponential Function

Step-by-step explanation:

Hi, an exponential function describes best the total number of rabbits in the colony over time, because the population tends to multiply by a specific rate over time.

An exponential function can be described as a growth function, for example in the form:

A = P (1 + r) t  

Where:  

p = original population  

r = growing rate (decimal form)  

t= years  

A = population after t years
