In any manner, the problem has to be treated using multilinear regression. Using a fourth degree polynomial, the predicted values would be $$\left( \begin{array}{cc} x & y & y_{calc} \\ -2. & +3. & -0.25\\ -8.
WebOct 25, 2016 · The normal equations will solve the general case. In your specific case, the values of b ( t) are symmetric around t = 1, so the parabola must be A ( t − 1) 2 + ( C − 1). Using the point at t = 1 we can see that C = 2, then a quick check shows A = 1 and we have b ( t) = ( t − 1) 2 + 1, which fits the points perfectly.
