Introduction

In mathematics, transformations of functions are essential concepts that help us understand how functions can be manipulated and represented in different ways. The given function $f(x)=\sqrt{x}$ undergoes several transformations, including left by 5, down by 2, and flipped over the x-axis. In this article, we will explore the order of these transformations and determine the equation of the transformed function.

Understanding the Transformations

To begin with, let's understand the individual transformations that are applied to the function $f(x)=\sqrt{x}$ .

Left by 5

When a function is shifted left by a certain value, it means that the graph of the function is shifted to the left by that value. In this case, the function $f(x)=\sqrt{x}$ is shifted left by 5 units. This can be represented as $f(x+5)=\sqrt{x+5}$ .

Down by 2

When a function is shifted down by a certain value, it means that the graph of the function is shifted downwards by that value. In this case, the function $f(x)=\sqrt{x}$ is shifted down by 2 units. This can be represented as $f(x)-2=\sqrt{x}-2$ .

Flipped Over the X-Axis

When a function is flipped over the x-axis, it means that the graph of the function is reflected over the x-axis. In this case, the function $f(x)=\sqrt{x}$ is flipped over the x-axis. This can be represented as $-f(x)=-\sqrt{x}$ .

Determining the Order of Transformations

Now that we have understood the individual transformations, let's determine the order in which they are applied to the function $f(x)=\sqrt{x}$ . The problem statement does not specify the order of transformations, so we will consider all possible orders.

Order 1: Left by 5, Down by 2, and Flipped Over the X-Axis

If the order of transformations is left by 5, down by 2, and flipped over the x-axis, then the equation of the transformed function can be represented as:

f(x)=-\left(\sqrt{x+5}-2\right)

Order 2: Down by 2, Left by 5, and Flipped Over the X-Axis

If the order of transformations is down by 2, left by 5, and flipped over the x-axis, then the equation of the transformed function can be represented as:

f(x)=-\left(\sqrt{x}-2\right)+5

Order 3: Flipped Over the X-Axis, Left by 5, and Down by 2

If the order of transformations is flipped over the x-axis, left by 5, and down by 2, then the equation of the transformed function can be represented as:

f(x)=-\left(\sqrt{x+5}\right)-2

Order 4: Flipped Over the X-Axis, Down by 2, and Left by 5

If the order of transformations is flipped over the x-axis, down by 2, and left by 5, then the equation of the transformed function can be represented as:

f(x)=-\left(\sqrt{x}-2\right)-5

Conclusion

In conclusion, the equation of the transformed function $f(x)=\sqrt{x}$ depends on the order of transformations applied to it. We have considered all possible orders of transformations and determined the equation of the transformed function for each order. The transformed function can be represented as:

f(x)=-\left(\sqrt{x+5}-2\right)

f(x)=-\left(\sqrt{x}-2\right)+5

f(x)=-\left(\sqrt{x+5}\right)-2

f(x)=-\left(\sqrt{x}-2\right)-5

The final answer is: $\boxed{-\left(\sqrt{x+5}-2\right)}$

Introduction

In our previous article, we explored the transformations of the function $f(x)=\sqrt{x}$ , including left by 5, down by 2, and flipped over the x-axis. We determined the equation of the transformed function for each possible order of transformations. In this article, we will answer some frequently asked questions related to the transformations of the function $f(x)=\sqrt{x}$ .

Q&A

Q: What is the effect of shifting a function left by a certain value?

A: When a function is shifted left by a certain value, it means that the graph of the function is shifted to the left by that value. This can be represented as $f(x+c)=f(x+c)$ , where $c$ is the value by which the function is shifted.

Q: What is the effect of shifting a function down by a certain value?

A: When a function is shifted down by a certain value, it means that the graph of the function is shifted downwards by that value. This can be represented as $f(x)-d=f(x)-d$ , where $d$ is the value by which the function is shifted.

Q: What is the effect of flipping a function over the x-axis?

A: When a function is flipped over the x-axis, it means that the graph of the function is reflected over the x-axis. This can be represented as $-f(x)=-f(x)$ .

Q: How do you determine the order of transformations?

A: To determine the order of transformations, you need to consider all possible orders of transformations and apply them to the function. In this case, we considered four possible orders of transformations: left by 5, down by 2, and flipped over the x-axis; down by 2, left by 5, and flipped over the x-axis; flipped over the x-axis, left by 5, and down by 2; and flipped over the x-axis, down by 2, and left by 5.

Q: What is the equation of the transformed function for each possible order of transformations?

A: The equation of the transformed function for each possible order of transformations is:

Left by 5, down by 2, and flipped over the x-axis: $f(x)=-\left(\sqrt{x+5}-2\right)$
Down by 2, left by 5, and flipped over the x-axis: $f(x)=-\left(\sqrt{x}-2\right)+5$
Flipped over the x-axis, left by 5, and down by 2: $f(x)=-\left(\sqrt{x+5}\right)-2$
Flipped over the x-axis, down by 2, and left by 5: $f(x)=-\left(\sqrt{x}-2\right)-5$

Q: How do you apply transformations to a function?

A: To apply transformations to a function, you need to follow these steps:

Determine the type of transformation (left, right, up, down, or flip).
Determine the value of the transformation (e.g., 5 units to the left).
Apply the transformation to the function using the appropriate notation (e.g., $f(x+c)$ for a left shift).

Conclusion

In conclusion, the transformations of the function $f(x)=\sqrt{x}$ are essential concepts in mathematics that help us understand how functions can be manipulated and represented in different ways. By understanding the effects of shifting, flipping, and other transformations, we can apply them to functions to create new and interesting graphs. We hope that this Q&A article has helped you understand the transformations of the function $f(x)=\sqrt{x}$ and how to apply them to functions.

Frequently Asked Questions

Q: What is the effect of shifting a function right by a certain value? A: When a function is shifted right by a certain value, it means that the graph of the function is shifted to the right by that value. This can be represented as $f(x-c)=f(x-c)$ , where $c$ is the value by which the function is shifted.
Q: What is the effect of shifting a function up by a certain value? A: When a function is shifted up by a certain value, it means that the graph of the function is shifted upwards by that value. This can be represented as $f(x)+d=f(x)+d$ , where $d$ is the value by which the function is shifted.
Q: How do you determine the equation of the transformed function? A: To determine the equation of the transformed function, you need to apply the transformations to the original function using the appropriate notation (e.g., $f(x+c)$ for a left shift).
Q: Can you give an example of a function that has been transformed? A: Yes, the function $f(x)=\sqrt{x}$ has been transformed in this article. The transformed function is $f(x)=-\left(\sqrt{x+5}-2\right)$ .
