Question 9 • *Integrated Math II Full
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?
Answer
A
y = 2(x – 20)2 + 6,000
B
y = –(x – 20)2 + 6,000C
y = –2(x – 20)2 + 6,000D
y = (x – 20)2 + 6,000
