Answer:

option A

The base is e^-1

Step-by-step explanation:

Given in the question a function, f(x) = (1/e)^{x}

This function can also be write as.

f(x) =(e^{-1})^{x}

by using Negative Exponent Rule

x^{-n}=\frac{1}{x^{n}}

This says that negative exponents in the numerator get moved to the denominator and become positive exponents.

Step-by-step explanation:

Let's represent Aaron's age with x and

Charlene's age with x+8

x+x+8=44

2x+8=44

2x=44-8

2x=36

x=36÷2

x=18

Aaron is 18 years old.

While Charlene is 18+8=26 years old.
