Understanding the Parent Function

The parent function, denoted as $$f(x)=x^3$$, is a fundamental cubic function that serves as a basis for various transformations and translations. This function has a characteristic S-shaped graph, with its vertex at the origin (0,0). The graph of $$f(x)$$ is symmetric about the origin and has a single inflection point at the origin.

Translation and Transformation of the Parent Function

When the parent function $$f(x)=x^3$$ is translated to form the graph of $$g(x)=(x+3)^3-4$$, several changes occur. The translation involves shifting the graph of $$f(x)$$ horizontally and vertically. The horizontal shift is achieved by adding 3 to the input variable x, resulting in the expression (x+3). This shift moves the graph of $$f(x)$$ 3 units to the left. The vertical shift is achieved by subtracting 4 from the output of the function, resulting in the expression -4. This shift moves the graph of $$f(x)$$ 4 units downward.

Identifying the Corresponding Point

To find the point on the graph of $$g(x)$$ that corresponds to the point (0,0) on the graph of $$f(x)$$, we need to substitute x=0 into the equation of $$g(x)$$. This will give us the y-coordinate of the corresponding point on the graph of $$g(x)$$.

Calculating the Corresponding Point

Substituting x=0 into the equation of $$g(x)$$, we get:

g(0)=(0+3)^3-4

g(0)=27-4

g(0)=23

Therefore, the point (0,0) on the graph of $$f(x)$$ corresponds to the point (0,23) on the graph of $$g(x)$$.

Understanding the Impact of Translation on the Graph

The translation of the parent function $$f(x)=x^3$$ to form the graph of $$g(x)=(x+3)^3-4$$ has a significant impact on the graph. The horizontal shift of 3 units to the left and the vertical shift of 4 units downward result in a new graph with a different vertex and inflection point. The corresponding point on the graph of $$g(x)$$, (0,23), is located 23 units above the origin, whereas the point (0,0) on the graph of $$f(x)$$ is located at the origin.

Conclusion

In conclusion, the translation of the parent function $$f(x)=x^3$$ to form the graph of $$g(x)=(x+3)^3-4$$ results in a new graph with a different vertex and inflection point. The corresponding point on the graph of $$g(x)$$, (0,23), is located 23 units above the origin, whereas the point (0,0) on the graph of $$f(x)$$ is located at the origin. This example illustrates the impact of translation on the graph of a function and highlights the importance of understanding the properties of the parent function.
