Calculate the relative (sub-space) topology with respect to the usual (metric) topology in R (the set of real numbers), for the following sub-sets of R:

X = Z, where Z represents the set of integers

Y = {0} U {1 / n | n is an integer such that n> 0}

Calculate (establish who are) the closed (relative) sets for the X and Y sub-spaces defined above.

Is {0} open relative to X?

Is {0} open relative to Y?

In RU (R is the reals, U is the usual topology), prove that any open interval (a, b) is homeomorphic to the interval (0, 1). (Hint: construct a function f : (a, b) → (0, 1) for which f(a) = 0 and f(b) = 1. Show that your map is a homeomorphism by showing that it is a continuous bijection with a continuous inverse.)

Let C(R) be the vector space of continuous functions from R to R with the usual addition and scalar multiplication. Determine if W is a subspace of C(R). Show algebraically and explain your answers thoroughly. a. W = C^n(R) = { f ∈ C(R) | f has a continuous nth derivative} b. W = {f ∈ C^2(R) | f''(x) + f(x) = 0} c. W = {f ∈ C(R) | f(-x) = f(x)}.

Let (X,d) be a metric space. The graph of f : X → R is the set {(x, y) E X X Rly = f(x)}. If X is connected and f is continuous, prove that the graph of f is also connected.
