Desmos is a free on-line graphing calculator that can be utilized to plot features, analyze knowledge, and carry out quite a lot of mathematical operations. One of many options of Desmos is the power to view discontinuities in features. A discontinuity is some extent the place the perform is just not outlined or the place the perform has a sudden change in worth.
There are two most important sorts of discontinuities: detachable discontinuities and non-removable discontinuities. Detachable discontinuities happen when the perform is just not outlined at some extent, however the restrict of the perform because the enter approaches the purpose exists. Non-removable discontinuities happen when the restrict of the perform because the enter approaches the purpose doesn’t exist.
To view discontinuities in Desmos, merely enter the perform into the enter area and click on the “Graph” button. Desmos will plot the perform and any discontinuities will likely be marked with a small circle. You can too use the “Desk” tab to view the values of the perform at particular factors, together with factors the place the perform is discontinuous.
1. Detachable discontinuities
Detachable discontinuities are factors the place a perform is just not outlined, however the restrict of the perform because the enter approaches the purpose exists. Because of this the perform will be “fastened” by redefining the perform on the level in order that the restrict is the same as the worth of the perform. For instance, the perform $f(x) = frac{x-1}{x-2}$ has a detachable discontinuity at $x=2$. It’s because the perform is just not outlined at $x=2$, however the restrict of the perform as $x$ approaches $2$ is $1$. To repair the discontinuity, we will merely redefine the perform at $x=2$ to be $f(2)=1$.

Discovering detachable discontinuities
To search out detachable discontinuities, we will search for factors the place the perform is just not outlined however the restrict of the perform exists. We are able to use Desmos to graph the perform and search for any factors the place there’s a gap within the graph. These holes characterize detachable discontinuities.

Fixing detachable discontinuities
As soon as now we have discovered the detachable discontinuities, we will repair them by redefining the perform at these factors in order that the restrict is the same as the worth of the perform. We are able to use Desmos to graph the perform once more to see if the discontinuities have been fastened.
Detachable discontinuities are necessary to think about when graphing features as a result of they will have an effect on the general form of the graph. By fixing detachable discontinuities, we will get a extra correct illustration of the perform.
2. Non-removable discontinuities
Non-removable discontinuities are factors the place the restrict of the perform because the enter approaches the purpose doesn’t exist. Because of this the discontinuity can’t be fastened by redefining the perform on the level. For instance, the perform $f(x) = frac{1}{x}$ has a non-removable discontinuity at $x=0$. It’s because the restrict of the perform as $x$ approaches $0$ doesn’t exist.

Discovering non-removable discontinuities
To search out non-removable discontinuities, we will search for factors the place the restrict of the perform because the enter approaches the purpose doesn’t exist. We are able to use Desmos to graph the perform and search for any factors the place the graph has a vertical asymptote. Vertical asymptotes characterize non-removable discontinuities.

Coping with non-removable discontinuities
As soon as now we have discovered the non-removable discontinuities, we will use Desmos to graph the perform once more, this time with the discontinuities marked as vertical asymptotes. It will give us a extra correct illustration of the perform.
Non-removable discontinuities are necessary to think about when graphing features as a result of they will have an effect on the general form of the graph. By understanding establish and cope with non-removable discontinuities, we will get a extra correct illustration of the perform.
3. Graphing discontinuities
Graphing discontinuities is a crucial a part of understanding how features behave. By graphing discontinuities, we will see the place the perform is just not outlined or has a sudden change in worth. This data can be utilized to research the perform and make predictions about its conduct.

Discovering discontinuities
Step one to graphing discontinuities is to seek out the factors the place the perform is just not outlined or has a sudden change in worth. This may be completed by wanting on the perform’s equation and figuring out any factors the place the denominator is zero or the place the perform is undefined. For instance, the perform $f(x) = frac{1}{x}$ has a discontinuity at $x=0$ as a result of the denominator is zero at that time.
-
Marking discontinuities
As soon as now we have discovered the discontinuities, we will mark them on the graph. This may be completed by drawing a small circle at every discontinuity. We are able to additionally use totally different colours or symbols to characterize various kinds of discontinuities. For instance, we may use a pink circle to characterize a detachable discontinuity and a blue circle to characterize a non-removable discontinuity.
-
Analyzing the graph
As soon as now we have graphed the discontinuities, we will analyze the graph to see how the perform behaves. We are able to search for patterns within the discontinuities and see how they have an effect on the general form of the graph. This data can be utilized to make predictions concerning the perform’s conduct at different factors.
