Option A: All real numbers is the right answer

Step-by-step explanation:

First of all, let us define domain

Domain is the set of all inputs to a function on which the function is defined

So

Given function is:

[tex]f(x) = 5.3^x[/tex]

The given function will not be undefined for any value of x as there is no denominator which will make the function approach infinity

Hence,

Option A: All real numbers is the right answer

Keywords: Domain, functions
