Understanding the Cube Root Parent Function

The cube root parent function, denoted as $f(x)=\sqrt[3]{x}$ , is a fundamental function in mathematics that represents the inverse operation of cubing a number. It is a one-to-one function, meaning that each value of $x$ corresponds to a unique value of $f(x)$ . The cube root function has a number of important properties, including:

Domain and Range: The domain of the cube root function is all real numbers, while the range is also all real numbers.
Graph: The graph of the cube root function is a curve that passes through the origin $(0,0)$ and has a horizontal asymptote at $y=0$ .
Symmetry: The cube root function is an odd function, meaning that it is symmetric about the origin.

Transformations of the Cube Root Parent Function

Transformations of the cube root parent function involve shifting, stretching, or compressing the graph of the function. There are four types of transformations that can be applied to the cube root function:

Vertical Shift: A vertical shift of the cube root function involves adding or subtracting a constant value to the function. This can be represented as $f(x) \pm c$ , where $c$ is a constant.
Horizontal Shift: A horizontal shift of the cube root function involves adding or subtracting a constant value to the input $x$ . This can be represented as $f(x \pm c)$ , where $c$ is a constant.
Vertical Stretch or Compression: A vertical stretch or compression of the cube root function involves multiplying the function by a constant value. This can be represented as $cf(x)$ , where $c$ is a constant.
Horizontal Stretch or Compression: A horizontal stretch or compression of the cube root function involves multiplying the input $x$ by a constant value. This can be represented as $f(cx)$ , where $c$ is a constant.

Applying Transformations to the Cube Root Parent Function

To find the function $g(x)$ , we need to apply a transformation to the cube root parent function $f(x)=\sqrt[3]{x}$ . The transformation involves shifting the graph of the cube root function up by 1 unit and to the right by 2 units.

Shifting the Graph Up by 1 Unit

To shift the graph of the cube root function up by 1 unit, we need to add 1 to the function. This can be represented as $f(x) + 1$ . Therefore, the function $g(x)$ can be written as:

g(x) = f(x) + 1

Shifting the Graph to the Right by 2 Units

To shift the graph of the cube root function to the right by 2 units, we need to add 2 to the input $x$ . This can be represented as $f(x-2)$ . Therefore, the function $g(x)$ can be written as:

g(x) = f(x-2) + 1

Combining the Transformations

Now that we have applied both transformations to the cube root parent function, we can combine them to find the final function $g(x)$ . Substituting $f(x-2)$ into the equation for $g(x)$ , we get:

g(x) = f(x-2) + 1

g(x) = \sqrt[3]{x-2} + 1

Conclusion

In conclusion, the function $g(x)$ is a transformation of the cube root parent function $f(x)=\sqrt[3]{x}$ . The transformation involves shifting the graph of the cube root function up by 1 unit and to the right by 2 units. Therefore, the function $g(x)$ can be written as:

g(x) = \sqrt[3]{x-2} + 1

This is option C in the given choices.

Final Answer

The final answer is:

C. $g(x)=\sqrt[3]{x-2}+1$
