Since the function has no restrictions, the domain of the function is of all real values, and the correct option is:
A. -∞ < x ∞.
<h3>What is the domain of a function?</h3>
The domain of a function is the set that contains all possible input values for the function.
In this problem, we have an exponential function, which has no restrictions in it's domain, such as a fraction or an even root, hence the domain of the function is of all real values, and the correct option is:
A. -∞ < x ∞.
