Prove that the above ilp is an ilp formulation of set cover. in other words, give a one-to-one mapping between feasible assignments to the variables x s and p subfamilies f 0 ⊆ f such that c(f 0 ) = u, and such that |f 0 | = s∈f x s .

Idon’t know what the answer is i wish i could

Bis your answer. it only holds the decimal numerals

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
