The following data points are expected to follow a functional variation of y=ax^2+bx+c . Obtain the values of a , b , and c by the method of least squares (Quadratic Regression). x: 1.21, 1.35, 2.40, 2.75, 4.50, 5.10, 7.10, 8.10 y: 1.20, 1.82, 5.00, 8.80, 19.5, 32.5, 55.0, 80.0 Solution Y= -18.29+10.77X.
