Given a starting guess of o 1 to find a minimum of the functionf()173 + 21z2 +4z +2, what is the approximation f of f used by the first step of Newton's method for optimization? Your answer should be a mathematical expression equivalent to one of the form a *h**2+b*h+c where a, b, and c, are replaced with the appropriate constants. Note that h ( - zo), but the expression you enter must be in terms of h. f (h)
