Let X be a topological space with the topology τ, and let A⊂X be a subset. Consider the subspace topology on A, denoted by τ_A, which is defined as τ_A={U∩A∣U∈τ}.Suppose X=R with the standard topology (where the open sets are unions of open intervals), and A=Q, the set of all rational numbers. Define a function f:A→R by f(x)=x^2.Determine whether f is continuous when A is considered with the subspace topology induced from R. Justify your answer by using the definition of continuity in topological spaces, which states that a function f:(X,τ_X)→(Y,τ_Y) is continuous if for every open set V∈τ_Y, the preimage f^{−1}(V) is an open set in τ_X.
This builds on example given in class; Let C_R be the set of all real valued continuous functions, and S_R be the subset of all symmetric real valued continuous functions. We have verified that S_R has the zero Vector, and is closed under pointwise addition. Show that the subset S_R is actually a Subspace by verifying the closure under scalar multiplication, namely, if r is any real number, and f is any Symmetric real valued function, Show that the function (rf) is also a symmetric real valued continuous function. Draw a graph to show f, rf and what makes the function (rf) symmetric.
