WebContinuity in Metric Spaces Remember, given f : X !Y and A ˆY the inverse image is a subset of X de–ned as: f 1(A) = fx 2X : f(x) 2AgˆX The inverse image is used to provide a characterization of continuous functions. Theorem Let (X;d) and (Y;ˆ) be metric spaces, and f : X !Y. Then f is continuous 1
