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

If x represents the year then that implies that y is equal to the number of new diseases every year. Therefore in order to solve this equation you need to input x. y= -2(15)^2 + 36(15) +6 Now solve, but please remember to use PEDMAS order in order to solve this problem. P= Parentheses E= Exponents D = Division M= Multiplication A= Addition S= Subtraction So solve the parentheses first y= -30^2 + 540 + 6 Now the exponent. y= 900 + 540 + 6 Now add them all together. y= 1446 So 1,446 is the number of new cases in year 15. y=
