In mathematics, transformations of parent functions are essential concepts in algebra and calculus. A parent function is a basic function from which other functions can be derived by applying various transformations. In this article, we will explore the transformation caused by the function $g(x) = 4|x+2|+1$ , which is a transformation of the parent function $f(x)$ .

What is a Parent Function?

A parent function is a basic function that serves as a reference point for other functions. It is a function that has been transformed in some way to create a new function. For example, the parent function $f(x) = x^2$ can be transformed into $g(x) = 2(x-3)^2+4$ by applying various transformations.

Understanding the Transformation $g(x) = 4|x+2|+1$

The transformation $g(x) = 4|x+2|+1$ is a transformation of the parent function $f(x)$ . To understand this transformation, we need to break it down into its components.

Vertical Stretch: The function $g(x) = 4|x+2|+1$ has a vertical stretch factor of 4. This means that the graph of $g(x)$ is 4 times the height of the graph of $f(x)$ .
Horizontal Shift: The function $g(x) = 4|x+2|+1$ has a horizontal shift of -2. This means that the graph of $g(x)$ is shifted 2 units to the left of the graph of $f(x)$ .
Reflection: The function $g(x) = 4|x+2|+1$ has a reflection across the y-axis. This means that the graph of $g(x)$ is a reflection of the graph of $f(x)$ across the y-axis.

Determining the Transformation Caused by Each of the Following

To determine the transformation caused by each of the following, we need to analyze the function $g(x) = 4|x+2|+1$ and compare it to the parent function $f(x)$ .

1. Vertical Stretch

A vertical stretch is a transformation that increases the height of the graph of a function. In the function $g(x) = 4|x+2|+1$ , the vertical stretch factor is 4. This means that the graph of $g(x)$ is 4 times the height of the graph of $f(x)$ .

2. Horizontal Shift

A horizontal shift is a transformation that moves the graph of a function to the left or right. In the function $g(x) = 4|x+2|+1$ , the horizontal shift is -2. This means that the graph of $g(x)$ is shifted 2 units to the left of the graph of $f(x)$ .

3. Reflection

A reflection is a transformation that flips the graph of a function across a line. In the function $g(x) = 4|x+2|+1$ , the reflection is across the y-axis. This means that the graph of $g(x)$ is a reflection of the graph of $f(x)$ across the y-axis.

4. Vertical Compression

A vertical compression is a transformation that decreases the height of the graph of a function. In the function $g(x) = 4|x+2|+1$ , there is no vertical compression. The vertical stretch factor is 4, which means that the graph of $g(x)$ is 4 times the height of the graph of $f(x)$ .

5. Horizontal Compression

A horizontal compression is a transformation that decreases the width of the graph of a function. In the function $g(x) = 4|x+2|+1$ , there is no horizontal compression. The horizontal shift is -2, which means that the graph of $g(x)$ is shifted 2 units to the left of the graph of $f(x)$ .

6. Reflection Across the X-Axis

A reflection across the x-axis is a transformation that flips the graph of a function across the x-axis. In the function $g(x) = 4|x+2|+1$ , there is no reflection across the x-axis. The reflection is across the y-axis, which means that the graph of $g(x)$ is a reflection of the graph of $f(x)$ across the y-axis.

7. Reflection Across the Y-Axis

A reflection across the y-axis is a transformation that flips the graph of a function across the y-axis. In the function $g(x) = 4|x+2|+1$ , the reflection is across the y-axis. This means that the graph of $g(x)$ is a reflection of the graph of $f(x)$ across the y-axis.

8. Translation

A translation is a transformation that moves the graph of a function to the left or right or up or down. In the function $g(x) = 4|x+2|+1$ , the translation is a horizontal shift of -2. This means that the graph of $g(x)$ is shifted 2 units to the left of the graph of $f(x)$ .

9. Rotation

A rotation is a transformation that rotates the graph of a function around a point. In the function $g(x) = 4|x+2|+1$ , there is no rotation. The graph of $g(x)$ is a reflection of the graph of $f(x)$ across the y-axis.

10. Dilation

A dilation is a transformation that enlarges or reduces the graph of a function. In the function $g(x) = 4|x+2|+1$ , the dilation is a vertical stretch with a factor of 4. This means that the graph of $g(x)$ is 4 times the height of the graph of $f(x)$ .

Conclusion

In conclusion, the transformation $g(x) = 4|x+2|+1$ is a transformation of the parent function $f(x)$ . The transformation caused by this function includes a vertical stretch, a horizontal shift, and a reflection across the y-axis. Understanding these transformations is essential in algebra and calculus, as it allows us to analyze and solve problems involving functions.
