math - Lagrange polynomial: Unexpected interpolation results -

i trying interpolate series of data points using 2nd lagrange polinomial. having point1:(5;100) point2: (9;17) point3: (12;17) and formula y=(x-x2)*(x-x3)/(x1-x2)*(x1-x3)*y1+ (x-x1)*(x-x3)/(x2-x1)*(x2-x3)*y2+ (x-x1)*(x-x2)/(x3-x1)*(x3-x2)*y3 it obvious quadratic function might not fit data.. example. but wonder why value surprisingly high x=7 . if not wrong y=1500 . is above formula correct? answer: in summary: for same x , can't have 2 different y values; violates definition of function. you missing brackets in formula! not (x-x2)*(x-x3)/(x1-x2)*(x1-x3) , ((x-x2)*(x-x3)) / ((x1-x2)*(x1-x3)) . back 1>, note interpolation formula has x3-x2 in denominator. if have tied values, dividing 0. how can make interpolation on such small data set? yet asking quadratic interpolation! follow-up: 1) fixed it. accidentally switched x , y values. points in format (y,x). ah, haha, no wonder. 2) thank you! brackets improved approximation. r...
