Final answer:
The statement that the sinusoidal axis is at y = 575 is true, as this represents the average rabbit population around which the population oscillates periodically.
Step-by-step explanation:
A rabbit population that rises and falls over time can be modeled by a sinusoidal function due to its periodic nature.
In this scenario, we are given specific dates when a minimum and an average population were recorded.
To analyze the given statements, we must understand the components of a sinusoidal function in the context of a rabbit population.
The claim that 'The sinusoidal axis is at y = 575' indicates that the average population level of rabbits serves as the horizontal axis around which the population oscillates.
This is typically true for sinusoidal functions representing periodic biological populations, where this axis is also known as the midline or equilibrium value.
True: The sinusoidal axis is at y = 575, indicating that this is the average population of rabbits, which is a common characteristic of such functions.
To fully determine the correctness of statements regarding the sinusoidal population model, we would need to consider additional specifics such as the amplitude, period, and phase shift, which are not provided by the given statements alone.
Hence, the statement that the sinusoidal axis is at y = 575 is true.
