Introduction

Graph transformations are a fundamental concept in mathematics, particularly in algebra and geometry. They involve changing the position, size, or orientation of a graph to create a new graph. In this article, we will explore the concept of graph transformations and determine which phrase best describes the translation from the graph $$y=(x+2)^2$$ to the graph of $$y=x^2+3$$.

What are Graph Transformations?

Graph transformations are a way of modifying a graph to create a new graph. There are several types of graph transformations, including:

Translations: Shifting the graph horizontally or vertically to create a new graph.
Dilations: Enlarging or shrinking the graph to create a new graph.
Rotations: Rotating the graph around a point to create a new graph.
Reflections: Reflecting the graph across a line or axis to create a new graph.

Translations

Translations involve shifting the graph horizontally or vertically to create a new graph. There are two types of translations:

Horizontal translation: Shifting the graph to the left or right.
Vertical translation: Shifting the graph up or down.

Horizontal Translation

A horizontal translation involves shifting the graph to the left or right. If the graph is shifted to the left, the x-coordinates of the graph are decreased by a certain value. If the graph is shifted to the right, the x-coordinates of the graph are increased by a certain value.

Vertical Translation

A vertical translation involves shifting the graph up or down. If the graph is shifted up, the y-coordinates of the graph are increased by a certain value. If the graph is shifted down, the y-coordinates of the graph are decreased by a certain value.

The Graph Transformation in Question

The graph transformation in question involves translating the graph $$y=(x+2)^2$$ to the graph of $$y=x^2+3$$. To determine which phrase best describes this translation, we need to analyze the two graphs.

Graph 1: $$y=(x+2)^2$$

The graph of $$y=(x+2)^2$$ is a parabola with a vertex at $(-2,0)$ . The graph is shifted 2 units to the left and 0 units up.

Graph 2: $$y=x^2+3$$

The graph of $$y=x^2+3$$ is a parabola with a vertex at $(0,3)$ . The graph is shifted 0 units to the left and 3 units up.

Determining the Translation

To determine which phrase best describes the translation from the graph $$y=(x+2)^2$$ to the graph of $$y=x^2+3$$, we need to compare the two graphs.

Horizontal translation: The graph $$y=x^2+3$$ is shifted 2 units to the right compared to the graph $$y=(x+2)^2$$. Therefore, the correct answer is not A or B.
Vertical translation: The graph $$y=x^2+3$$ is shifted 3 units up compared to the graph $$y=(x+2)^2$$. Therefore, the correct answer is not C or D.

Conclusion

Based on the analysis of the two graphs, the correct answer is:

2 units right and 3 units up

This is because the graph $$y=x^2+3$$ is shifted 2 units to the right and 3 units up compared to the graph $$y=(x+2)^2$$.

Final Answer

The final answer is:

A. 2 units left and 3 units up

No, this is incorrect. The correct answer is:

C. 2 units right and 3 units up

Why is this the correct answer?

Introduction

Graph transformations are a fundamental concept in mathematics, particularly in algebra and geometry. They involve changing the position, size, or orientation of a graph to create a new graph. In this article, we will explore the concept of graph transformations and answer some common questions related to this topic.

Q: What is a graph transformation?

A: A graph transformation is a way of modifying a graph to create a new graph. There are several types of graph transformations, including translations, dilations, rotations, and reflections.

Q: What is a translation?

A: A translation is a type of graph transformation that involves shifting the graph horizontally or vertically to create a new graph. There are two types of translations: horizontal translation and vertical translation.

Q: What is a horizontal translation?

A: A horizontal translation involves shifting the graph to the left or right. If the graph is shifted to the left, the x-coordinates of the graph are decreased by a certain value. If the graph is shifted to the right, the x-coordinates of the graph are increased by a certain value.

Q: What is a vertical translation?

A: A vertical translation involves shifting the graph up or down. If the graph is shifted up, the y-coordinates of the graph are increased by a certain value. If the graph is shifted down, the y-coordinates of the graph are decreased by a certain value.

Q: How do I determine the type of graph transformation?

A: To determine the type of graph transformation, you need to analyze the graph and identify the changes that have been made. You can do this by comparing the original graph with the new graph and identifying the changes in the x-coordinates and y-coordinates.

Q: What are some common graph transformations?

A: Some common graph transformations include:

Translations: Shifting the graph horizontally or vertically to create a new graph.
Dilations: Enlarging or shrinking the graph to create a new graph.
Rotations: Rotating the graph around a point to create a new graph.

Q: How do I graph a translated function?

A: To graph a translated function, you need to follow these steps:

Identify the type of translation (horizontal or vertical).
Determine the amount of translation (how far the graph is shifted).
Graph the original function.
Shift the graph horizontally or vertically by the determined amount.

Q: What are some real-world applications of graph transformations?

A: Graph transformations have many real-world applications, including:

Computer graphics: Graph transformations are used to create 3D models and animations.
Engineering: Graph transformations are used to design and optimize systems, such as bridges and buildings.
Science: Graph transformations are used to model and analyze data in fields such as physics and biology.
