Introduction

In mathematics, functions can be transformed in various ways, including reflection and translation. Reflection involves flipping a function over a line, while translation involves shifting the function horizontally or vertically. In this article, we will explore the reflection of a function over the line y = 0 and its translation 4 units to the right.

Reflection over the Line y = 0

To reflect a function over the line y = 0, we need to multiply the function by -1. This is because the line y = 0 acts as a mirror, and multiplying the function by -1 will flip it over this line.

Given Function

The given function is g(x) = 5^x. To reflect this function over the line y = 0, we need to multiply it by -1.

Reflected Function

The reflected function is:

g(x) = -5^x

Translation 4 Units to the Right

To translate a function 4 units to the right, we need to replace x with (x - 4). This will shift the function 4 units to the right.

Translated Function

The translated function is:

g(x) = -5^(x-4)

Analysis of Options

Now, let's analyze the options given:

A. f(x) = 5^(x-4)

This option is incorrect because it does not reflect the function over the line y = 0.

B. f(x) = 5^(-(x-4))

This option is also incorrect because it does not reflect the function over the line y = 0.

C. f(x) = -5^(x-4)

This option is correct because it reflects the function over the line y = 0 and translates it 4 units to the right.

Conclusion

In conclusion, to reflect a function over the line y = 0 and translate it 4 units to the right, we need to multiply the function by -1 and replace x with (x - 4). The correct function is f(x) = -5^(x-4).
