What kind of transformation converts the graph of $f(x)=4(x+5)^2-4$ into the graph of $g(x)=4x^2-4$?

Understanding the Problem

The problem requires us to determine the type of transformation that occurs when the graph of the function $f(x)=4(x+5)^2-4$ is converted into the graph of the function $g(x)=4x^2-4$ . To solve this problem, we need to analyze the given functions and identify the type of transformation that takes place.

Analyzing the Functions

The function $f(x)=4(x+5)^2-4$ can be rewritten as $f(x)=4x^2+40x+100-4$ , which simplifies to $f(x)=4x^2+40x+96$ . On the other hand, the function $g(x)=4x^2-4$ is already in its simplest form.

Identifying the Transformation

To identify the type of transformation that occurs, we need to compare the two functions. We can see that the function $f(x)$ has a horizontal shift of 5 units to the left, as indicated by the term $(x+5)^2$ . This means that the graph of $f(x)$ is shifted 5 units to the left compared to the graph of $g(x)$ .

Conclusion

Based on the analysis, we can conclude that the transformation that converts the graph of $f(x)=4(x+5)^2-4$ into the graph of $g(x)=4x^2-4$ is a translation of 5 units to the right.

Final Answer

The final answer is B. Translation 5 units right.

Discussion

The problem requires us to analyze the given functions and identify the type of transformation that takes place. We need to rewrite the function $f(x)$ in its simplest form and compare it with the function $g(x)$ . By identifying the horizontal shift, we can determine the type of transformation that occurs.

Importance of Understanding Transformations

Understanding transformations is crucial in mathematics, as it helps us to analyze and solve problems involving functions. By identifying the type of transformation that occurs, we can determine the effect of the transformation on the graph of the function.

Transformations have numerous real-world applications, including physics, engineering, and computer science. In physics, transformations are used to describe the motion of objects, while in engineering, they are used to design and optimize systems. In computer science, transformations are used to develop algorithms and data structures.

Common Types of Transformations

There are several types of transformations, including:

Translation: A translation is a transformation that moves a graph a certain distance in the horizontal or vertical direction.
Dilation: A dilation is a transformation that enlarges or reduces a graph by a certain scale factor.
Rotation: A rotation is a transformation that rotates a graph by a certain angle around a fixed point.
Reflection: A reflection is a transformation that reflects a graph across a certain line or axis.

Conclusion

In conclusion, the transformation that converts the graph of $f(x)=4(x+5)^2-4$ into the graph of $g(x)=4x^2-4$ is a translation of 5 units to the right. Understanding transformations is crucial in mathematics, as it helps us to analyze and solve problems involving functions.
