Question

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

O A. All real numbers
O B. x>0
O C. x< 0
O D. y > 0

Answer 1

All real values

Explanation:

Given

`f(x) = ((1)/(3))^x`

Required

Determine the domain

The domain of a function are the values of x that makes the function to be defined.

From the given function, we can see that no single value of x will make the function become undefined.

Hence, the domain is:

x = (-∞, +∞)

In other words, the domain implies that all real numbers.

Hence:

Option (A) answers the question.
