How do I find a quadratic model for the set of values?
(-2,-8),(0,-2),(4,-62)
---------------------------
Use the form ax^2 + bx + c = y
----------
With each of the points, substitute the corresponding x and y values
into the form to get three equations in three unknowns: a, b, and c.
Then solve the systerm for a, b, and c.
