Determining continuity of a function

WebA function is discontinuous at a point a a if it fails to be continuous at a a. The following procedure can be used to analyze the continuity of a function at a point using this … WebTo be continuous at a point (say x=0), the limit as x approaches 0 must equal to the actual function evaluated at 0. The function f (x)=1/x is undefined at 0, since 1/0 is undefined. …

You can substitute 4 into this function to get an answer: 8. If you look at the function algebraically, it factors to this: which is 8. Both sides of the equation are 8, so f (x) is continuous at x = 4 ... WebDetermining Continuity. When we say a function f is continuous, we usually mean it's continuous at every real number.In other words, it's continuous on the interval (-∞, ∞). Some examples of continuous functions that are continuous at every real number are: polynomials, e x, sin(x), and cos(x). If we add, subtract, multiply, or compose … WebA discontinuity is a point at which a mathematical function is not continuous. Given a one-variable, real-valued function y= f (x) y = f ( x), there are many discontinuities that can occur. The simplest type is called a removable discontinuity.
