Answer:
The growth factor for the rabbit population can be calculated using the formula:
Growth factor = 1 + (percent increase as a decimal)
In this case, the rabbit population increases 2.3% each year, so the growth factor can be calculated as:
Growth factor = 1 + (0.023) = 1.023
Therefore, the growth factor for the rabbit population is 1.023, meaning that the population will increase by a factor of 1.023 each year.
