Answer:
[tex]x\in(-\infty,\infty)[/tex]
Step-by-step explanation:
The given function is [tex]f(x)=5^x[/tex]
Domain is the set of x values for which the function is defined.
The function [tex]f(x)=5^x[/tex] is an exponential function and for any real values of x, the function f(x) will be defined.
Therefore, we can conclude that the domain of the function is all real numbers.
In interval notation, the domain of f(x) is
[tex]x\in(-\infty,\infty)[/tex]
