Start with the equation .. a*x^2 + b*x + c = y Put in your x and y values, and you will get three linear equations in the unknowns a, b, c. These can be solved by the method of your choice. (Cramer's method works well.) Your numbers here give …

A plane is defined by a point and two non-parallel vectors. Some linear sum of the vectors and the point will define any point in the plane. Any two vectors will do, hence there will be an infinite number of possible parametric equations for a plane…
