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

Discovering detachable discontinuities
To seek out detachable discontinuities, we will search for factors the place the operate is just not outlined however the restrict of the operate exists. We will use Desmos to graph the operate and search for any factors the place there’s a gap within the graph. These holes symbolize detachable discontinuities.
-
Fixing detachable discontinuities
As soon as now we have discovered the detachable discontinuities, we will repair them by redefining the operate at these factors in order that the restrict is the same as the worth of the operate. We will use Desmos to graph the operate once more to see if the discontinuities have been mounted.
Detachable discontinuities are vital to contemplate 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 operate.
2. Non-removable discontinuities
Non-removable discontinuities are factors the place the restrict of the operate because the enter approaches the purpose doesn’t exist. Which means that the discontinuity can’t be mounted by redefining the operate on the level. For instance, the operate $f(x) = frac{1}{x}$ has a non-removable discontinuity at $x=0$. It’s because the restrict of the operate as $x$ approaches $0$ doesn’t exist.
-
Discovering non-removable discontinuities
To seek out non-removable discontinuities, we will search for factors the place the restrict of the operate because the enter approaches the purpose doesn’t exist. We will use Desmos to graph the operate and search for any factors the place the graph has a vertical asymptote. Vertical asymptotes symbolize 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 operate once more, this time with the discontinuities marked as vertical asymptotes. This may give us a extra correct illustration of the operate.
Non-removable discontinuities are vital to contemplate when graphing features as a result of they will have an effect on the general form of the graph. By understanding the best way to establish and cope with non-removable discontinuities, we will get a extra correct illustration of the operate.
3. Graphing discontinuities
Graphing discontinuities is a vital a part of understanding how features behave. By graphing discontinuities, we will see the place the operate is just not outlined or has a sudden change in worth. This info can be utilized to investigate the operate and make predictions about its habits.

Discovering discontinuities
Step one to graphing discontinuities is to seek out the factors the place the operate is just not outlined or has a sudden change in worth. This may be carried out by wanting on the operate’s equation and figuring out any factors the place the denominator is zero or the place the operate is undefined. For instance, the operate $f(x) = frac{1}{x}$ 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 carried out by drawing a small circle at every discontinuity. We will additionally use totally different colours or symbols to symbolize various kinds of discontinuities. For instance, we may use a purple circle to symbolize a detachable discontinuity and a blue circle to symbolize 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 operate behaves. We will search for patterns within the discontinuities and see how they have an effect on the general form of the graph. This info can be utilized to make predictions in regards to the operate’s habits at different factors.
