Which function represents g(x), a reflection of f(x) = (10)^x across the x-axis?
g(x) = -2/5(10)^x
g(x) = -2/5(1/10)^x
g(x) =2/5(1/10)^-x
g(x) = 2/5(10)^-x

Option A.

Step-by-step explanation:

Note: The given function should be instead of .

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

Therefore, the correct option is A.

total = principal × ( 1 + rate ) ^ years

total = 600 * (1.04)^5

total = 729.99

answer is c
