Introduction

In mathematics, the concept of parent functions and their transformations is a crucial aspect of understanding various mathematical functions. A parent function is a basic function that has been modified or transformed in some way to create a new function. In this article, we will explore the concept of parent functions and their transformations, specifically focusing on the graph of the parent function $f(x)=x^3$ and its translation to form the graph of $g(x)=(x+5)^3-6$ .

Understanding Parent Functions

A parent function is a basic function that has been modified or transformed in some way to create a new function. In the case of the function $f(x)=x^3$ , it is a basic cubic function that has been modified to create various other functions. The graph of the parent function $f(x)=x^3$ is a cubic curve that opens upwards, with its vertex at the origin (0,0).

Translation of the Parent Function

The graph of the parent function $f(x)=x^3$ is translated to form the graph of $g(x)=(x+5)^3-6$ . This translation involves shifting the graph of the parent function $f(x)=x^3$ horizontally and vertically. The horizontal shift is 5 units to the left, and the vertical shift is 6 units downwards.

Understanding the Translation

To understand the translation, let's break it down into two parts: the horizontal shift and the vertical shift.

Horizontal Shift

The horizontal shift is 5 units to the left, which means that the graph of the parent function $f(x)=x^3$ is shifted 5 units to the left. This can be represented as $x \rightarrow x+5$ . In other words, the x-coordinate of each point on the graph of the parent function $f(x)=x^3$ is increased by 5.

Vertical Shift

The vertical shift is 6 units downwards, which means that the graph of the parent function $f(x)=x^3$ is shifted 6 units downwards. This can be represented as $y \rightarrow y-6$ . In other words, the y-coordinate of each point on the graph of the parent function $f(x)=x^3$ is decreased by 6.

Finding the Corresponding Point

The point $(0,0)$ on the graph of $f(x)$ corresponds to which point on the graph of $g(x)$ ? To find the corresponding point, we need to apply the translation to the point $(0,0)$ .

Applying the Horizontal Shift

The horizontal shift is 5 units to the left, so we need to subtract 5 from the x-coordinate of the point $(0,0)$ . This gives us $x = 0 - 5 = -5$ .

Applying the Vertical Shift

The vertical shift is 6 units downwards, so we need to subtract 6 from the y-coordinate of the point $(0,0)$ . This gives us $y = 0 - 6 = -6$ .

Conclusion

In conclusion, the point $(0,0)$ on the graph of $f(x)$ corresponds to the point $(-5,-6)$ on the graph of $g(x)$ . This demonstrates how the translation of the parent function $f(x)=x^3$ to form the graph of $g(x)=(x+5)^3-6$ affects the corresponding points on the two graphs.
