 Find a quadratic function that models the data. -The table shows the number of new AIDS cases among women in the U.S. in six consecutive years. Data are in thousands rounded to the nearest hundred.   Let  \mathrm{x}=1  correspond to 1988 and let  \mathrm{f}(\mathrm{x})   be the number of new AIDS cases (in thousands)  among women in the U.S. in year  x . Using the point  (1,3.0)   as the vertex and  (6,16.1)   as the other point, determine a quadratic function  f(x) =a(x-h) ^{2}+k  that models the data. A)   f(x) =0.764(x-1) ^{2}-3.0  B)   f(x) =0.824(x-1) ^{2}+3.0  C)   f(x) =0.364(x-1) ^{2}+3.0  D)   f(x) =0.524(x-1) ^{2}+3.0
Let x=1\mathrm{x}=1 correspond to 1988 and let f(x) \mathrm{f}(\mathrm{x}) be the number of new AIDS cases (in thousands) among women in the U.S. in year xx . Using the point (1,3.0) (1,3.0) as the vertex and (6,16.1) (6,16.1) as the other point, determine a quadratic function f(x) =a(xh) 2+kf(x) =a(x-h) ^{2}+k that models the data.


A) f(x) =0.764(x1) 23.0f(x) =0.764(x-1) ^{2}-3.0
B) f(x) =0.824(x1) 2+3.0f(x) =0.824(x-1) ^{2}+3.0
C) f(x) =0.364(x1) 2+3.0f(x) =0.364(x-1) ^{2}+3.0
D) f(x) =0.524(x1) 2+3.0f(x) =0.524(x-1) ^{2}+3.0
