WebThe following proposition lists some properties of continuous functions, all of which are consequences of our results about limits in Section 2.3. Proposition Suppose the functions f and g are both continuous at a point c and k is a constant. Then the functions which take on the following values for a variable x are also continuous at c: kf(x ... WebThe function 1/x is not uniformly uniformly continuous. This is because the δ necessarily depends on the value of x. A uniformly continuous function is a one for which, once I …
