which is the domain of the function f(x) = negative five-sixths (three-fifths) superscript x?

(answer choices are attached)

oh and i know the answer is definitely isn't c, i've already tried that one.

Set of all real numbers.

Step-by-step explanation:

Here, the given function,

f(x) = Negative five-sixths (three-fifths) Superscript x

Since, it is an exponential function,

We know that,

An exponential function is defined for every real number,

Thus, f(x) will also defined for all real numbers,

That is,

Domain of f(x) = Set of all real numbers.
