Question

One can fit a curve y=f(x) to data points(x1,y1), (x2,y2),.....,(xN,yN) by minimizing the sum of the squared errors:

(f(x;) – Y:)².
i=1
The sum of the squared errors is an overall measure of how much f(x) deviates from the data.
Here, you'll find the quadratic function of the form f(x) = ax? + b which best fits the points (1,0), (5, 5), (7, 10).
(i) For the given data, find the sum of the squared errors E, which is a function that depends on the coefficients a and b of the quadratic function.
E(a, b)
