Introduction

In mathematics, functions are used to describe the relationship between variables. A function $f(x)$ is a rule that assigns to each input value $x$ a unique output value $f(x)$ . In this article, we will discuss the function $f(x)=\frac{1}{3}(6)^x$ and its reflection across the $x$ -axis, denoted as $g(x)$ .

The Function $f(x)$

The function $f(x)$ is defined as $f(x)=\frac{1}{3}(6)^x$ . This function is an exponential function, where the base is $6$ and the exponent is $x$ . The coefficient $\frac{1}{3}$ is a constant that scales the output of the function.

Reflection Across the $x$ -Axis

A reflection across the $x$ -axis is a transformation that flips a function over the $x$ -axis. This means that for every point $(x, y)$ on the original function, the reflected function has the point $(x, -y)$ . In other words, the $y$ -coordinate of each point is negated.

Table of Values for $g(x)$

To graph the reflection of $f(x)$ across the $x$ -axis, we need to create a table of values for $g(x)$ . Since $g(x)$ is a reflection of $f(x)$ , we can use the same $x$ -values as $f(x)$ , but we need to negate the corresponding $y$ -values.

Creating the Table of Values

To create the table of values for $g(x)$ , we can use the following steps:

Choose a set of $x$ -values.
Calculate the corresponding $y$ -values for $f(x)$ using the equation $f(x)=\frac{1}{3}(6)^x$ .
Negate the $y$ -values to obtain the corresponding $y$ -values for $g(x)$ .

Example

Let's choose the following $x$ -values: $x = -2, -1, 0, 1, 2$ . We can calculate the corresponding $y$ -values for $f(x)$ using the equation $f(x)=\frac{1}{3}(6)^x$ .

$x$	$f(x)$
-2	$\frac{1}{3}(6)^{-2}$
-1	$\frac{1}{3}(6)^{-1}$
0	$\frac{1}{3}(6)^0$
1	$\frac{1}{3}(6)^1$
2	$\frac{1}{3}(6)^2$

Now, we can negate the $y$ -values to obtain the corresponding $y$ -values for $g(x)$ .

$x$	$g(x)$
-2	$-\frac{1}{3}(6)^{-2}$
-1	$-\frac{1}{3}(6)^{-1}$
0	$-\frac{1}{3}(6)^0$
1	$-\frac{1}{3}(6)^1$
2	$-\frac{1}{3}(6)^2$

Conclusion

In this article, we discussed the function $f(x)=\frac{1}{3}(6)^x$ and its reflection across the $x$ -axis, denoted as $g(x)$ . We created a table of values for $g(x)$ by negating the corresponding $y$ -values of $f(x)$ . This table of values can be used to graph $g(x)$ .

The function $f(x)$ is an exponential function with a base of $6$ and an exponent of $x$ . The coefficient $\frac{1}{3}$ scales the output of the function. The reflection of $f(x)$ across the $x$ -axis is denoted as $g(x)$ , and we created a table of values for $g(x)$ by negating the corresponding $y$ -values of $f(x)$ .
