Question 109702: i don't even know where to start with this one. how do you write a quadratic function in standard form whose graph passes through the points (1,1), (0,-2), and (2,8). and solve algebraically?

You can put this solution on YOUR website! i don't even know where to start with this one. how do you write a quadratic function in standard form whose graph passes through the points (1,1), (0,-2), and (2,8). and solve algebraically?
----------
I'll tell you and let you do it.
-----------------
Quadratic form is ax^2+bx+c = y
Substitute each x/y pair values into the form to generate
three equations with variables a,b,and c.
----------------
solve the system of equations to find a, b, and c.
