# Expanding the Width of Parabolas on Desmos

Parabolas are a type of curve that people often use in mathematics to represent various physical phenomena. But when it comes to creating a parabola on Desmos, you might sometimes feel that the shape is not up to your expectation or need. But fear not – there are ways to make a parabola wider on Desmos. In this article, we will explore some techniques that you can use to adjust the size of your parabola to fit your requirements.

Before we dive into the techniques, let’s first understand what a parabola is. A parabolic curve is a U-shaped curve that is symmetric around a vertical line known as the axis of symmetry. It is created by plotting points that are equidistant from a fixed point, known as the focus, and a fixed straight line, known as the directrix. On Desmos, the default size of a parabola may not always be satisfactory, especially if you need a wider curve. However, using the following techniques, you can easily modify the size of your parabola to fit your needs.

Introduction:

Desmos is a powerful online graphing calculator that helps students and professionals create accurate graphs, charts, and diagrams with ease. One of the most common questions that people ask is “how can I make a parabola wider on Desmos?” In this article, we’ll explore some simple steps that you can take to adjust the width of your parabola and create the perfect graph.

10 Steps on How to Make a Parabola Wider on Desmos:

## Step 1: Define Your Parabola

The first step in creating a wider parabola on Desmos is to define your initial curve. To create a basic parabola, you can use the equation y = x². Once you’ve plugged in this equation on Desmos, you’ll see your parabola graph appear.

## Step 2: Adjust the Range of your Parabola

By default, the range of the parabola on Desmos is set to -10 to 10 on both x and y-axes. If you want to make your parabola wider, you can adjust the range by clicking on the wrench icon at the top left corner of the screen. Once you’ve done this, change the range to -15 to 15 or whatever range you think works best for your graph.

## Step 3: Adjust the Window Settings

The next thing you need to do is adjust the window settings of your parabola. Click the wrench icon again and this time, select “Custom…” from the “Window Settings” section. In the X-min field, enter a number that represents the far left of your window. In the X-max field, enter a number that represents the far right of your window. Repeat this process for the Y-min and Y-max fields.

## Step 4: Adjusting the A Value

One of the easiest ways to make your parabola wider is to adjust the “a” value in your parabola equation. The larger the a value, the wider the parabola will be. To adjust the a value, simply change the equation to y = ax² and play around with different numbers until you get the width you want.

## Step 5: Adjusting the B Value

Another way to make your parabola wider is by adjusting the b value in your equation. The b value affects the position of the parabola on the x-axis. Increase the b value to shift the parabola to the right or decrease it to move it to the left. However, keep in mind that changing b will not affect the width of the parabola, only its position on the graph.

## Step 6: Use the Slider Tool

Another tool that you can use to make your parabola wider on Desmos is the slider tool. You can find this tool by clicking the “Add Item” button at the top of the page and then selecting “Slider.” You can then add sliders to different variables in your parabola equation, such as “a” or “b,” and use the slider to change the width of your parabola in real-time.

## Step 7: Adding Points to Your Graph

If you want to make your parabola wider but not taller, you can add points to your graph on either side of the curve. To do this, click the “+” icon at the top left of the screen and then select “Point.” Once you’ve done this, add points to the left and right edges of the parabola and then drag them outward to widen the curve.

## Step 8: Use the Zoom Tool

Another way to make your parabola wider on Desmos is to use the zoom tool. This tool allows you to zoom in and out of your graph, making it easier to adjust the width of your parabola. To use this tool, click on the magnifying glass icon at the top left of the screen and then use your mouse to zoom in or out of the graph.

## Step 9: Additional adjustments

In addition to the above, there are many other adjustments you can make to your graph to make your parabola wider. For example, you can adjust the line style to a thicker line, change the color, or even add shading to your graph. These adjustments won’t directly affect the width of your parabola, but they can help make it stand out on the page.

## Step 10: Save Your Graph

Finally, once you’ve made all the adjustments necessary to create your perfect parabola, make sure to save your graph by clicking the “Export” button at the top left of the screen. You can then choose to download your graph as a PNG or PDF file or save it directly to your Desmos account.
