The rabbit population, y, in hundreds of rabbits, in an area x years since 1990 can be determined using this function: y = - 0.1x2 + 50. What is happening to the rabbit population? Offer a possible explanation for how the population is changing.

Y=-0.1x^2+50

This is a quadratic with a negative acceleration of - 0.2, a velocity of - 0.2x, and an initial value of 50.

The rabbit population is decreasing rapidly, perhaps due to the area in which they live being developed or by the introduction of a predator population ...
