Aids Cases 1993 year the to s correspond 0 x where , 430 76 2 N by ed approximat be can ds in thousan cases aids of N number cumulative the 2003 to 1993 from 2 = + + - = x x
Use the equation to find N for each year in the table . 1 422 1993, putting x=0, N = -2(0)^2+76(0)+430 = 430 4 1995, putting x=2, N = -2(2)^2+76(2)+430 = 574 4 1997, putting x=4, N = -2(4)^2+76(4)+430 = 702 4 1999, putting x=6, N = -2(6)^2+76(6)+430 = 814 4 2001, putting x=8, N = -2(8)^2+76(8)+430 = 910
