Question:

Equation (10-5) gives a least-squares estimate for curve fitting. This equation was derived by finding the point at which the slope of the cost function is zero. The maximum of a function also occurs at the point at which the slope is zero. Show that (10-5) is a minimum, not a maximum, of the cost function.

Equation 10-5N B = argmine(k) B k=0 (10-5)
