How to Write Cube Root in Desmos

Desmos is a powerful graphing calculator that can be used to visualize mathematical functions. It can also be used to perform calculations, such as finding the cube root of a number. In this tutorial, we will show you how to write the cube root function in Desmos. We will also show you how to use the cube root function to find the cube root of a number.

Writing the Cube Root Function in Desmos

To write the cube root function in Desmos, you can use the following syntax:

y = cbrt(x)

where `x` is the number whose cube root you want to find. For example, to find the cube root of 8, you would use the following equation:

y = cbrt(8)

This will plot the cube root function on the Desmos graphing calculator. You can then use the slider to change the value of `x` and see how the cube root function changes.

Finding the Cube Root of a Number

To find the cube root of a number using Desmos, you can simply enter the number into the cube root function. For example, to find the cube root of 8, you would enter the following equation into the Desmos graphing calculator:

y = cbrt(8)

This will return the value of the cube root of 8, which is approximately 2.4495.

In this tutorial, we showed you how to write the cube root function in Desmos and how to use it to find the cube root of a number. We hope you found this tutorial helpful. For more information on Desmos, please visit the [Desmos website](https://www.desmos.com/).

1	Type the expression “x” into the Desmos graphing calculator.
2	Click the “Graph” button to see the graph of the cube root function.

What is the cube root function?

The cube root function is a mathematical function that takes a number as its input and returns the cube root of that number. In other words, it returns the number that, when cubed, gives the original number. For example, the cube root of 8 is 2, because 2 cubed is 8.

The cube root function is written as x, where x is the number whose cube root is being calculated. For example, the cube root of 8 can be written as 8.

The cube root function is a decreasing function, which means that as the input increases, the output decreases. This is because the cube of a larger number is larger than the cube of a smaller number. For example, the cube of 2 is 8, while the cube of 4 is 64.

The cube root function is also a continuous function, which means that it can be graphed without any breaks or gaps. The graph of the cube root function is a curve that has a minimum point at 0.

How to write the cube root function in Desmos?

To write the cube root function in Desmos, you can use the following syntax:

y = x

where x is the input variable. For example, the following code will graph the cube root function from -5 to 5:

y = x

plot(y, -5, 5)

The resulting graph will look like this:

You can also use the cube root function to solve equations. For example, the following code will solve the equation x = 2 for x:

x = solve(x = 2)

The output of this code will be 8, which is the cube root of 2.

The cube root function is a useful function that can be used to solve a variety of problems. It is important to understand the properties of the cube root function in order to use it effectively.

How to Write Cube Root in Desmos?

The cube root function in Desmos is a function that returns the cube root of a given number. To write the cube root function in Desmos, you can use the following syntax:

cubeRoot(x)

where `x` is the number whose cube root you want to find.

For example, to find the cube root of 8, you would use the following function:

cubeRoot(8)

This would return the value of 2.

You can also use the cube root function to graph the cube root function. To do this, you would use the following syntax:

y = cubeRoot(x)

where `y` is the y-coordinate of the point on the graph and `x` is the x-coordinate of the point on the graph.

For example, the following graph shows the cube root function from -5 to 5:

Examples of Using the Cube Root Function in Desmos

The cube root function can be used to solve a variety of problems in Desmos. Here are a few examples:

• To find the cube root of a number: You can use the cube root function to find the cube root of any number. For example, to find the cube root of 8, you would use the following function:

cubeRoot(8)

This would return the value of 2.

• To graph the cube root function: You can use the cube root function to graph the cube root function. To do this, you would use the following syntax:

y = cubeRoot(x)

where `y` is the y-coordinate of the point on the graph and `x` is the x-coordinate of the point on the graph.

For example, the following graph shows the cube root function from -5 to 5:

• To solve a cubic equation: You can use the cube root function to solve a cubic equation. To do this, you would first need to convert the cubic equation into the form `ax^3 + bx^2 + cx + d = 0`. Then, you would use the following steps to solve the equation:

1. Find the cube root of `-d/a`.
2. Substitute this value into the equation `x = (-b +- sqrt(b^2 – 4ac))/2a`.
3. Solve for `x`.

For example, to solve the equation `x^3 – 3x^2 – 10x – 24 = 0`, you would first need to convert the equation into the form `ax^3 + bx^2 + cx + d = 0`. This gives us the equation `x^3 – 3x^2 – 10x – 24 = (x – 4)(x^2 + 2x + 6)`.

Then, we would find the cube root of `-d/a`. In this case, `d = -24` and `a = 1`, so the cube root of `-d/a` is `-4`.

Finally, we would substitute this value into the equation `x = (-b +- sqrt(b^2 – 4ac))/2a`. This gives us the two solutions `x = 2` and `x = -6`.

• To find the volume of a cube: You can use the cube root function to find the volume of a cube. To do this, you would use the following formula:

V = a^3

where `V` is the volume of the cube, and `a` is the length of one side of the cube.

For example, to find the volume of a cube with a side length of 3, you would use the following formula:

V = 3^3 = 27

This means that the volume of the cube is 27 cubic units.
