PLEASE PUT SOLUTION IN THE FORM OF A FORMAL PROOF. Let (X, d) be a metric space and give R the usual Euclidean metric. Assume that f:XR is continuous. (a) S the set {x E X | f(x) a} is open for all a R. (b) Show that the set (xEXIf(x) a is closed for all a E R. how thait
#realanalysis Metric and distance 1. Show that the discrete metric satisfies the properties of a metric. 2. Compute the distances dalf.g) and d(f.g) when f.ge CO, are the functions defined by f(r) and g() 3. Show that the following functions do not define metrics on R. Metric and distance 1. Show that the discrete metric satisfies the properties of a metric. 2. Compute the distances dalf.g) and d(f.g) when f.ge CO, are the functions defined by f(r) and g() 3....
Discrete Mathematics. (a) Use the method of generalizing from the generic particular in a direct proof to show that the sum of any two odd integers is even. See the example on page 165 of the 5th edition of Discrete Mathematics with Applications, Metric Version for how to lay this proof out. (b) Determine whether 0.151515... (repeating forever) is a rational number. Give reasoning. (c) Use proof by contradiction to show that for all integers n, 3n + 2 is...
Show that the given map is surjective. Please give a detailed, thorough formal explanation/proof. It's somewhat obvious it is surjective, but I don't know how to start the proof. We are supposed to take y element of codomain and show that there exists f(x) = y but where is the codomain and where is the domain? Somewhat confused since we have two binary structures. Thanks! 7.

(c) (6 points) Show a formal proof that the height of a Red-Black Tree h with n nodes, is at most 2.log(n + 1), i.e. h < 2.log(n + 1). Show and proof any intermediate claim in order to prove the final claim.
Please answer in the style of a formal proof and thoroughly reference any theorems, lemmas or corollaries utilized. BUC stands for bounded uniformly continuous Let (X, d) be a metric space. Show that the set V of Lipschitz continu- ous bounded functions from X to R is a dense linear subspace of BUC(X, R). Since, in general, V #BUC(X, R), V is not a closed subset of BUC(X, R). Hint: For f EBUC(X, R) define the sequence (fr) by fn(x)...
Please answer in the style of a formal proof and thoroughly reference any theorems, lemmas or corollaries utilized. Problem 3. (Chebyshev nodes) Let x; = - cos(ja/N), j = 0,...N. Assuming N is even, show that 21 – xo = O(1/N2) and {N/2 – XN/2–1 = O(1/N).

note that M is a metric space please i need the question 7 for the proof and explain it ! thanks ! 7. Let V C M be open sets such that Vn is compact, Vn # Ø, and Vnc Vn=1: Prove Y 7. Let V C M be open sets such that Vn is compact, Vn # Ø, and Vnc Vn=1: Prove Y
please explain it to me clearly 6 Proof of the dual theorem Proof: We will assume that the primal LP is in canonical form Maximize Zr, such that Arb 20 12 Its dual is Minimize W·ry, such that ATy c (no sign constraints on y). Step 1: Suppose xB is the basic variables in the optimal BFS (say r*) f follows from the above discussion that Row (0) of the optimal tableau will be the Prianal LP. It Basic VariableRow2...
