We introduce some properties (B) and (C) of functions of two variables such that (B) is an essential weakening of quasi-continuity and (C) is valid, in particular, for functions taking values in separable metriz
Any non-constant function from the plane to {0,1} is of necessity discontinuous. If you compose such a function with a path on which the function is constant, then the result is a constant function from (an interval of) the reals to {0,1}, which is continuous. Here the y-axis lie...
What is a continuous function? Different types (left, right, uniformly) in simple terms, with examples. Check continuity in easy steps.
Definition of Continuity of a Function of Two Variables A function of two variables is continuous at a point (a,b) in an open region R if f(a,b) is equal to the limit of f(x,y) as (x,y) approaches (a,b). In limit notation: ). , ( ) , ( lim ) , ( ) , ( b...
Let f, g be two continuous functions on D. Prove that the functions h(x) = min{f(x), g(x)} and H(x) = max{f(x),g(x)} are continuous on D. Are h and H uniformly continuous on D in f and g are? Prove that if...
