If (1, 8) is a point on the graph of \ =\ ax^2\ +\ bx\ +\ c)
, then ^2\ +\ b(1)\ +\ c\ =\ 8)
.
If (2, 3 is a point on the graph of , then ^2\ +\ b(2)\ +\ c\ =\ 3)
If (4, -31) is a point on the graph of , then ^2\ +\ b(4)\ +\ c\ =\ -31)
Simplifying:
Solve the 3X3 system of equations to determine the a, b, and c coefficients of the desired function.
