Desmos: How To Graph Piecewise
In this day and age, technology has made it possible to do almost anything with just a few clicks. When it comes to graphing, Desmos is one of the most popular tools out there. It is a free online graphing calculator that has helped countless students and professionals alike in their mathematical endeavors. However, not everyone knows how to graph piecewise functions on Desmos. In this article, we will look at how to do just that.
What is a Piecewise Function?
A piecewise function is a function that is defined differently on different parts of its domain. In other words, a piecewise function is a function that has different rules for different intervals. For example, consider the following piecewise function:
f(x) = 2x, x < 0
f(x) = x^2, x ≥ 0
This function is defined as 2x when x is less than 0 and x^2 when x is greater than or equal to 0.
How to Graph Piecewise Functions on Desmos
Graphing piecewise functions on Desmos is easy. All you need to do is enter the function in the calculator and Desmos will do the rest. Let's take a look at how to graph the function above on Desmos.
- Open the Desmos website.
- Click on the plus sign in the top left corner to create a new graph.
- In the input bar at the top, type in the first part of the function: 2x.
- Click on the curly brace symbol ({) to add a new line.
- In the second line of the input bar, type in the second part of the function: x^2.
- Click on the "plus" icon next to the input bar to graph the function.
Once you have followed these steps, Desmos will graph the piecewise function for you.
Customizing the Graph
Desmos allows you to customize your graph in various ways. You can change the color of the lines, add labels to the axes, and even add shading to the graph. Let's take a look at how to customize the graph of our piecewise function.
- Click on the wrench icon in the top right corner of the graph.
- From here, you can change the color of the lines by clicking on "Colors".
- To add labels to the axes, click on "Axes" and then "Labels".
- To add shading to the graph, click on "Expressions" and then "Shade".
By customizing your graph, you can make it easier to read and understand.
Using Desmos for Homework and Tests
Desmos is not just a tool for graphing piecewise functions. It can also be used for homework and tests. In fact, many teachers now require their students to use Desmos for their math homework.
If you are using Desmos for homework or a test, make sure you are familiar with the tool beforehand. This will help you save time and avoid mistakes.
Conclusion
Graphing piecewise functions on Desmos is easy and straightforward. By following the steps outlined in this article, you can graph any piecewise function you encounter. Additionally, by customizing your graph, you can make it easier to read and understand. Whether you are a student or a professional, Desmos is a tool that can help you succeed in your mathematical endeavors.
