**Transformations of Quadratic Functions: A Comparative Analysis**

Introduction

In mathematics, transformations of functions are essential concepts that help us understand how different operations can change the graph of a function. When it comes to quadratic functions, understanding these transformations is crucial for analyzing and solving various mathematical problems. In this article, we will explore the transformations applied to the graph of $f(x)=x^2$ to change it into the graph of $g(x)=-x^2+16x-44$ .

Understanding the Original Function

The original function is $f(x)=x^2$ . This is a quadratic function in the form of $f(x)=ax^2$ , where $a=1$ . The graph of this function is a parabola that opens upwards, with its vertex at the origin $(0,0)$ . The parabola is symmetric about the y-axis, and its equation can be written in the form $y=ax^2$ .

Understanding the Transformed Function

The transformed function is $g(x)=-x^2+16x-44$ . This is also a quadratic function, but it has been modified to have a different equation. The graph of this function is also a parabola, but it opens downwards, and its vertex is not at the origin. To understand the transformations applied to the graph of $f(x)=x^2$ , we need to analyze the equation of $g(x)$ and compare it with the equation of $f(x)$ .

Comparing the Equations

Comparing the equations of $f(x)$ and $g(x)$ , we can see that the equation of $g(x)$ has been modified in several ways. The coefficient of $x^2$ has been changed from $1$ to $-1$ , which means that the parabola opens downwards instead of upwards. The linear term $16x$ has been added, which shifts the parabola to the left. The constant term $-44$ has been added, which shifts the parabola downwards.

Analyzing the Transformations

To analyze the transformations applied to the graph of $f(x)=x^2$ , we need to consider the following:

Reflection: The coefficient of $x^2$ has been changed from $1$ to $-1$ , which means that the parabola has been reflected about the x-axis.
Translation: The linear term $16x$ has been added, which means that the parabola has been shifted to the left by $8$ units.
Vertical Shift: The constant term $-44$ has been added, which means that the parabola has been shifted downwards by $44$ units.

Conclusion

In conclusion, the graph of $f(x)=x^2$ has been transformed into the graph of $g(x)=-x^2+16x-44$ by applying the following transformations:

Reflection: The parabola has been reflected about the x-axis.
Translation: The parabola has been shifted to the left by $8$ units.
Vertical Shift: The parabola has been shifted downwards by $44$ units.

These transformations have changed the graph of $f(x)=x^2$ into the graph of $g(x)=-x^2+16x-44$ . Understanding these transformations is essential for analyzing and solving various mathematical problems involving quadratic functions.
