Question

What is the domain of F(x) = (1/3) ^x

A. x > 0

B. All real numbers

C. x < 0

D. y > 0

Answer 1

The function \( F(x) = \left( \frac{1}{3} \right)^x \) is an exponential function. Exponential functions are defined for all real numbers, meaning you can input any real number for \( x \) and get a valid output.

Therefore, the domain of \( F(x) \) is:

**B. All real numbers**
