The population, y, of a small town can be represented using a quadratic model. The maximum population, 6,000 people, occurred 20 years after record keeping began. Five years later, the population was 5,950. If x represents the number of years after record keeping began, which equation represents the given scenario? y = 2 (x - 20) 2 + 6,000 y = - 2/9 (x - 20) 2 + 6,000 y = - 2 (x - 20) 2 + 6,000 y = 2/9 (x - 20) 2 + 6,000
