Introduction

In mathematics, graphing functions is a crucial aspect of understanding and visualizing mathematical relationships. When it comes to graphing functions involving radicals, such as cube roots, it's essential to understand the behavior of the function and how it affects the graph. In this article, we will explore the graph of the function $y=\sqrt[3]{x-5}$ and determine which graph represents this function.

Understanding the Function

The given function is $y=\sqrt[3]{x-5}$. This function involves a cube root, which means that the value inside the radical is raised to the power of 1/3. To understand the behavior of this function, let's break it down into its components.

  • The function has a horizontal shift of 5 units to the right, since the value inside the radical is $x-5$.
  • The function has a vertical shift of 0 units, since there is no constant term outside the radical.
  • The function has a cube root, which means that the value inside the radical is raised to the power of 1/3.

Graphing the Function

To graph the function $y=\sqrt[3]{x-5}$, we need to consider the following:

  • The function is a cube root function, which means that it will have a characteristic "S" shape.
  • The function has a horizontal shift of 5 units to the right, which means that the graph will be shifted 5 units to the right.
  • The function has a vertical shift of 0 units, which means that the graph will not be shifted vertically.

Analyzing the Graphs

Let's analyze the graphs provided and determine which one represents the function $y=\sqrt[3]{x-5}$.

Graph A

Graph A is a cube root function with a horizontal shift of 5 units to the right. However, the graph is not a perfect cube root function, as it has a slight curvature.
