If (1, 7) is a point on the graph of \ =\ ax^2\ +\ bx\ +\ c) , then ^2\ +\ b(1)\ +\ c\ =\ 7) .
If (2, 2) is a point on the graph of , then ^2\ +\ b(2)\ +\ c\ =\ 2)
If (4, -32) is a point on the graph of , then ^2\ +\ b(4)\ +\ c\ =\ -32)
Simplifying:
Solve the 3X3 system of equations to determine the a, b, and c coefficients of the desired function.
