SpletSolution: We observe that we can readily estimate the size of f (x) when x > 1 because x 1. It follows that. 0 ≤ x^2 + 2x + 1 ≤ x^2 + 2x^2 + x^2 = 4x^2. whenever x > 1. Consequently, we can take C = 4 and k = 1 as witnesses to show that f (x) is O (x^2). That is, f (x) = x^2 + 2x + 1 1. (Note that it is not necessary to use absolute values ... Spletf (x) is a function of x, but f' (x) is the derivative with respect to what seems to make sense. In terms of a-level f' (x) pretty much means dy/dx, but you should realise that d (f (x))/dx = f' (x) doesn't require a y. As for the post, it depends what you are differentiating with respect to but I assume it is p (i.e. do you want dq / dp ?).

SpletPred 1 dnevom · Because x j is a binary variable, ∏ j ∈ J (1 − p i j x j) can be rewritten as ∏ j ∈ J (1 − p i j) x j, and according to the logarithm transformation, it can be further rewritten as e ∑ j ∈ J x j log (1 − p i j). Then, let γ i j = − log (1 − p i j) ≥ 0, and set γ i j to be a large enough number M when p i j = 1. Berman ...
