Once again, informally we say that f has a removable discontinuity if there is a hole in the function, but f has a nonremovable discontinuity if there is a jump or a vertical asymptote. Take note of any holes, any asymptotes, or any jumps. Be sure you see from example 1 that the graph of a polynomial function is continuous on the entire real line, and therefore has no holes, jumps, or gaps. Consider an open interval i that contains a real number c.
If a discontinuity exists, then describe the type of discontinuity and its physical feature on a. B has a removable point discontinuity at x 0 c has a nonremovable oscillation discontinuity at x 0 d has an nonremovable infinite discontinuity at x 0.

Pages 58 are posters to post in the corners of your classroom infinite discontinuity, jump discontinuity, point discontinuity, and continuous. If the general limit and fc are the same then the function is continuous at c. Function f x is continuous if, meaning that the limit of f x as x approaches a from either direction is equal to f a, as long as a is in the domain of f x.

Here is a set of practice problems to accompany the continuity section of the limits chapter of the notes for paul dawkins calculus i course at lamar university. As noted in the hint for this problem when dealing with a rational expression in which both the numerator and denominator are continuous as we have here since both are polynomials the only points in which the rational expression will be discontinuous will be where we have division by zero.

For each graph, determine where the function is discontinuous. Describe the behavior of f x to the left and right of each vertical asymptote. How to classify discontinuities practice problems explained step. The material was further updated by zeph grunschlag. Available for prealgebra, algebra 1, geometry, algebra 2, precalculus, and calculus. Analyze functions for intervals of continuity or points of discontinuity. For rational functions, we try to algebraically remove the discontinuity by canceling. Create the worksheets you need with infinite calculus. These all represent discontinuities, and just one discontinuity is enough to make your function a discontinuous function. Worksheet by kuta software llc calculus practice 1. The limit of a rational power of a function is that power of the limit of the function, provided the latter is a real number. We will now take a closer look at limits and, in particular, the limits of functions. Continuity and discontinuity a function is continuous if it can be drawn without picking up the pencil. If a function is not a continuous function, then it is discontinuous.
To begin with, we will look at two geometric progressions. The continuity of a function and its derivative at a given point is discussed. Jump discontinuity a jump discontinuity occurs when the righthand and lefthand limits exist but are not equal. Software for math teachers that creates exactly the worksheets you need in a matter of minutes. What graphical manifestation would f x have at x 2.
