Question

Find the sum of the squared errors for the linear model f(x) and the quadratic model g(x) using the given points.
f(x) = 2.0x − 3, g(x) = 0.09x^2 + 1.6x − 3
(−1, −4), (1, −2), (2, 0), (4, 6), (6, 9)
linear model-?
quadratic model- ?

Answer 1

Let me get this right - you want me to square all these differences to save you the trouble of doing it. I already took the course. Let us see what you did.
