Use the sequential criterion for the absence of uniform continuity to show that the function f(0, 1) - 1 given by f(x) = 1/-x) is not uniformly continuous. Theorem 4.4.5 (Sequential Criterion for Absence of Uniform Conti- nuity). A function /: A → R fails to be uniformly continuous on A if and only if there erists a particular to > 0 and two sequences (in) and (y) in A satisfying In - yn — but if(n)-f(n) Co.
