**Reflection Across the x-axis: A Mathematical Explanation**

Understanding Reflection Across the x-axis

When a function is reflected across the x-axis, its graph is flipped upside down. This means that if we have a function f(x) and we want to reflect it across the x-axis, we need to multiply the entire function by -1. In mathematical terms, this can be represented as g(x) = -f(x).

The Original Function

Let's consider the original function f(x) = (2/5)(10)^x. This function represents an exponential growth curve, where the base is 10 and the coefficient is 2/5.

Reflection Across the x-axis

To reflect the function f(x) across the x-axis, we need to multiply the entire function by -1. This will flip the graph upside down, resulting in a new function g(x) that represents the reflection of f(x) across the x-axis.

The Reflected Function

The reflected function g(x) can be represented as g(x) = -f(x). Substituting the original function f(x) = (2/5)(10)^x into this equation, we get:

g(x) = -(2/5)(10)^x

Simplifying the Reflected Function

To simplify the reflected function g(x), we can rewrite it as:

g(x) = -2/5 * (10)^x

This is the final form of the reflected function g(x).

Conclusion

In conclusion, when a function is reflected across the x-axis, its graph is flipped upside down. To reflect a function f(x) across the x-axis, we need to multiply the entire function by -1. The reflected function g(x) can be represented as g(x) = -f(x), and in this case, g(x) = -2/5 * (10)^x.
