The cubic root function, denoted as $f(x)=\sqrt[3]{x}$ , is a fundamental concept in mathematics that has numerous applications in various fields, including algebra, geometry, and calculus. In this article, we will explore how the graph of the cubic root function changes when it is replaced by $f(x+c)$ , where $c$ is a positive constant.

The Original Graph of $f(x)=\sqrt[3]{x}$

The graph of the cubic root function is a simple, yet fascinating, curve that exhibits unique properties. To understand the behavior of the graph, let's first examine its key features. The cubic root function is defined for all real numbers, and its domain is the set of all real numbers, denoted as $\mathbb{R}$ . The range of the function is also the set of all real numbers, $\mathbb{R}$ .

The graph of the cubic root function is a continuous, increasing curve that passes through the origin, $(0,0)$ . As $x$ increases, the value of $f(x)$ also increases, and vice versa. The graph has a horizontal asymptote at $y=0$ , which means that as $x$ approaches infinity, the value of $f(x)$ approaches zero.

Replacing $f(x)$ with $f(x+c)$

Now, let's consider the effect of replacing $f(x)$ with $f(x+c)$ , where $c$ is a positive constant. This transformation involves shifting the graph of the original function $f(x)$ to the left by $c$ units. In other words, the new function $f(x+c)$ is obtained by replacing $x$ with $x+c$ in the original function $f(x)$ .

To understand the behavior of the new function $f(x+c)$ , let's analyze its key features. The domain of the new function is the same as the original function, $\mathbb{R}$ . However, the range of the new function is also the set of all real numbers, $\mathbb{R}$ .

The graph of the new function $f(x+c)$ is a shifted version of the original graph of $f(x)$ . Since $c$ is a positive constant, the graph of $f(x+c)$ is shifted to the left by $c$ units. This means that for every point $(x,y)$ on the original graph of $f(x)$ , there is a corresponding point $(x-c,y)$ on the new graph of $f(x+c)$ .

Effect of Shifting on the Graph

The shift in the graph of $f(x+c)$ has a significant impact on its behavior. Since the graph is shifted to the left by $c$ units, the value of $f(x+c)$ is greater than the value of $f(x)$ for the same input $x$ . This is because the graph is shifted to the left, which means that the same input $x$ corresponds to a greater output value $f(x+c)$ .

To illustrate this concept, let's consider an example. Suppose we have the function $f(x)=\sqrt[3]{x}$ , and we replace it with $f(x+2)$ . The graph of $f(x+2)$ is a shifted version of the original graph of $f(x)$ , and it is shifted to the left by 2 units.

Conclusion

In conclusion, the graph of the cubic root function $f(x)=\sqrt[3]{x}$ changes significantly when it is replaced by $f(x+c)$ , where $c$ is a positive constant. The new function $f(x+c)$ is obtained by shifting the original graph of $f(x)$ to the left by $c$ units. This shift has a profound impact on the behavior of the graph, and it results in a greater output value for the same input $x$ .

Answer to the Question

Based on our analysis, we can conclude that the graph of $f(x)=\sqrt[3]{x}$ shifts to the left when it is replaced by $f(x+c)$ , where $c$ is a positive constant. Therefore, the correct answer to the question is:

C. The graph shifts left.

Final Thoughts

The cubic root function is a fundamental concept in mathematics that has numerous applications in various fields. Understanding the behavior of the graph of the cubic root function is essential for solving problems in algebra, geometry, and calculus. By analyzing the effect of shifting on the graph of the cubic root function, we can gain a deeper understanding of the properties of this function and its applications in various fields.
