Please answer both part. Thanks.
In the power method, let rk d(x(k+1))/ф(z(k)). We know that limk-oo rk Show that the relative errors obey 1- Ai where the numbers ck form a convergent (and hence bounded) sequence. (Continuation) Show that rk +1-λι-(c+&J(rk-A) where Icl < 1 and limn-o0 Sk 0, so that Aitken acceleration is applicable.

(c) The sequence is divergent to oo (d) The sequence is divergent to -oo (e) The sequence is increasing f) The sequence is decreasing (g) The sequence is non-decreasing (h) The sequence isn't decreasing (i) The sequence is bounded above (j) The sequence is not...
(5) Let f: [0, 1 R. We say that f is Hölder continuous of order a e (0,1) if \f(x) -- f(y)| . , y sup [0, 1] with 2 # 1£l\c° sup is finite. We define Co ((0, 1]) f: [0, 1] -R: f is Hölder continuous of order a}. = (a) For f,gE C ([0, 1]) define da(f,g) = ||f-9||c«.

We were unable to transcribe this imageWe were unable to transcribe this imagec) Let y - Ara. Suppose that we see when p - 2 and w - 1 then x-3 and y-8. Also when p-1 and w 1.5, then x-4 and y - 10. Can we identify the parameters of the production function from these two observations? Graph what an economist who didn't know the functional form of the production function would conclude about the production set.

Problem 1 Suppose X ~ fx(x), and let Y = aX + b. We know that E(Y) = aE(X) b, and Var(X)a2Var(X). What about the density of Y, fy(y)? Assuming a > 0. Calculate fy(y) using the following two methods (1) Let Fx() P(X x). Calculate Fy(y) = P(Y < y) in terms of Fx. Then calculate fy (2) Calculate Y (y, y + Ay)) Ay fr(y) (3) Give geometric explanations of your result
Please all thank you
