Question

The number of cases of a new disease can be modeled by the quadratic regression equation y = –2x2 + 36x + 6, where x represents the year. Which is the best prediction for the number of new cases in year 15? A. 194 B. 96 C. 328 D. 614

Answer 1

y = –2x^2 + 36x + 6

x=15

y = -2*15^2 +36(15) +6

y= -2(225) +540+6

y=-450+540+6

y=96

Answer: Choice B
