Question

a parabola contains the following points.(-5,8),(2,-3),(3-1) Which of the following systems of equations could be solved in order to find the equation that corresponds to this parabola?

Answer 1

The general form of a parabola equation:

y = a*x^2 + b*x + c

For each point:

8 = 25*a - 5*b + c

-3 = 4*a + 2*b + c

-1 = 9*a + 3*b + c

This is our system of equations
