Consider the given function is
We need to find the function which represents a reflection of f(x) across the x-axis.
If a function f(x) is reflected across the x-axis, then the new function is
Using this rule, we get
![[\because f(x)=\dfrac{2}{5}(10)^x]](https://tex.z-dn.net/?f=%5B%5Cbecause%20f%28x%29%3D%5Cdfrac%7B2%7D%7B5%7D%2810%29%5Ex%5D)
Therefore, the correct option is A.
