let (0,3) and (1,9)and (-1,1) be given points in a parablola. Determine a b and c
The general form of a parabola is
If (0,3) is on the parabola then the equation must be true when x = 0 and y = 3. Substituting these values into the equation gives
Simularily if (1,9) and (-1,1) are on the parabola then
Solve this pair of equations for a and b.Cheers,
