Let us show convergence of this algorithm. Let w∗ be the ultimate solution, and let rho = minj yj (w∗ ) T xj . 1. Show that (w(k) ) T w∗ ≥ krho. 2. Show kw(k)k 2 2 ≤ kR2 for R = maxj kxjk2, by proving that kw(k)k 2 2 ≤ kw(k−1)k 2 2 + kxjk 2 2 . 3. Using 1. and 2., prove that (w(k) ) T w∗ kw(k)k2 ≥ √ k rho R (15) Show that this further impl

The linear equation is: y=ax+b

The answer should be c.

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
