Where is x discontinuous

Explanation : Rewrite the function in its factored form. If possible, find the type of discontinuity, if any:. Explanation : By looking at the denominator of , there will be a discontinuity.

Since the common factor is existent, reduce the function. Find the point of discontinuity for the following function:. There is no point of discontinuity for the function. Explanation : Start by factoring the numerator and denominator of the function. There is no point fo discontinuity for this function. Find a point of discontinuity for the following function:. There are no discontinuities for this function. There are no points of discontinuity for this function.

Find a point of discontinuity in the following function:. There is no point of discontinuity for this function. Copyright Notice. View Pre-Calculus Tutors. Josh Certified Tutor.

If both the limit of f of x as x approaches k and f of k exist, and f is not continuous at k, then what is the value of k?

So we have to find a k where f is not continuous at k, but f of k is defined. And the limit as x approaches k of f of x is also defined. So the easiest ones to spot out just with our eyes might just to be to see where f is not continuous, where f is not continuous.

So you see here when x is equal to negative 2, the function is not continuous. It jumps from up here. The property which describes this characteristic is called continuity.

If a function has a hole, the three conditions effectively insist that the hole be filled in with a point to be a continuous function. Rather than define whether a function is continuous or not, it is more useful to determine where a function is continuous.

To prove a function is not continuous, it is sufficient to show that one of the three conditions stated above is not met. When a function is not continuous at a point, then we can say it is discontinuous at that point.
