2. Consider the linear equation Ax = b, AERmxn, beR. When m > n it is often the case that this equation is over-determined and no solution x exists. In this case we seek a “best” solution in the least squares sense. That is we solve minimize 3 || Ax – 6|| BERN Define f: RM → R by f(x) := 3 || Ax – b||2. (a) Show that f can be written as a quadratic function, that is, a...
