Introduction

In mathematics, parent functions serve as the foundation for various transformations. Understanding these transformations is crucial in graphing and analyzing functions. In this article, we will explore the transformation of the parent function f(x)=x13f(x)=\sqrt[3]{x-1} to g(x)=x13g(x)=\sqrt[3]{-x-1}. We will analyze the graphical representation of both functions and determine which graph correctly shows the functions f(x)f(x) and g(x)g(x).

Understanding the Parent Function

The parent function f(x)=x13f(x)=\sqrt[3]{x-1} is a cube root function with a horizontal shift of 1 unit to the right. This means that the graph of f(x)f(x) is a cube root curve shifted 1 unit to the right.

Transforming the Parent Function

To transform the parent function f(x)f(x) to g(x)g(x), we need to apply two transformations:

  1. Horizontal Reflection: The function g(x)g(x) is obtained by reflecting the function f(x)f(x) across the y-axis. This means that the graph of g(x)g(x) is a mirror image of the graph of f(x)f(x) across the y-axis.
  2. Vertical Shift: The function g(x)g(x) is also obtained by shifting the function f(x)f(x) 1 unit to the left. This means that the graph of g(x)g(x) is a cube root curve shifted 1 unit to the left.

Graphical Representation

To determine which graph correctly shows the functions f(x)f(x) and g(x)g(x), we need to analyze the graphical representation of both functions.

Graph A

Graph A shows the function f(x)=x13f(x)=\sqrt[3]{x-1} as a cube root curve shifted 1 unit to the right. However, it does not show the correct transformation of the function g(x)=x13g(x)=\sqrt[3]{-x-1}.

Graph B

Graph B shows the function g(x)=x13g(x)=\sqrt[3]{-x-1} as a cube root curve shifted 1 unit to the left. This graph correctly represents the transformation of the parent function f(x)f(x) to g(x)g(x).

Graph C

Graph C shows the function f(x)=x13f(x)=\sqrt[3]{x-1} as a cube root curve shifted 1 unit to the right. However, it does not show the correct transformation of the function g(x)=x13g(x)=\sqrt[3]{-x-1}.

Graph D

Graph D shows the function g(x)=x13g(x)=\sqrt[3]{-x-1} as a cube root curve shifted 1 unit to the left. However, it does not show the correct transformation of the function f(x)=x13f(x)=\sqrt[3]{x-1}.

Conclusion

Based on the graphical analysis, the correct graph that shows the functions f(x)f(x) and g(x)g(x) is Graph B. This graph correctly represents the transformation of the parent function f(x)f(x) to g(x)g(x).

Answer

The correct answer is B.

Discussion

The transformation of the parent function f(x)=x13f(x)=\sqrt[3]{x-1} to g(x)=x13g(x)=\sqrt[3]{-x-1} involves two transformations: a horizontal reflection and a vertical shift. The graphical representation of both functions shows that Graph B correctly represents the transformation of the parent function f(x)f(x) to g(x)g(x).

Key Takeaways

  • The parent function f(x)=x13f(x)=\sqrt[3]{x-1} is a cube root function with a horizontal shift of 1 unit to the right.
  • The function g(x)=x13g(x)=\sqrt[3]{-x-1} is obtained by reflecting the function f(x)f(x) across the y-axis and shifting it 1 unit to the left.
  • The graphical representation of both functions shows that Graph B correctly represents the transformation of the parent function f(x)f(x) to g(x)g(x).
