This is because the δ necessarily depends on the value of x. A uniformly continuous function is a one for which, once I specify an ε there is a δ that work for all x and y. For example, the function g(x) = √x is uniformly continuous. Given ε, pick δ = ε 2. female wrestling cradle pin

Nevertheless, the continuity of a function is such an important property that we need a precise definition of continuity at a point:

WebbThe continuity of a function says if the graph of the function can be drawn continuously without lifting the pencil. The differentiability is the slope of the graph of a function at any point in the domain of the function. Both continuity and differentiability, are complementary functions to each other.
