WebDefinition: Continuity of a Function at a Point. Let 𝑎 ∈ ℝ. We say that a real-valued function 𝑓 ( 𝑥) is continuous at 𝑥 = 𝑎 if l i m → 𝑓 ( 𝑥) = 𝑓 ( 𝑎). A useful property of continuity at 𝑥 = 𝑎 is that we can sketch the graph of 𝑓 ( 𝑥) near 𝑥 = 𝑎 without lifting the pen off the paper. To study ... WebFor functions that are “normal” enough, we know immediately whether or not they are continuous at a given point. Nevertheless, the continuity of a function is such an important property that we need a precise definition of continuity at a point:

In its simplest form the domain is all the values that go into a function. We may be able to choose a domain that makes the function continuous Example: 1/ (x−1) At x=1 we have: 1/ (1−1) = 1/0 = undefined So there is a "discontinuity" at x=1 f (x) = 1/ (x−1) So f (x) = 1/ (x−1) over all Real Numbers is NOT continuous WebIn mathematical terms, the definition of continuity is as follows. A function f (x) is said to be continuous at a point if the following conditions are met. The function at that point exists being finite. The left and right-hand limit of the function is present.

WebA function is said to be continuous on an interval, or subset of its domain, if and only if it is continuous at each point of the interval. The sum, difference, and product of continuous functions with the same domain are also continuous, as is the quotient, except at points at which the denominator is zero. WebContinuity A function is continuous at a point when the value of the function equals its limit. Discontinuities can be seen as "jumps" on a curve or surface. The sum, difference, product and composition of continuous functions are also continuous.
