Answer:

All real numbers.

D is the correct option.

Explanation:

The given function is
f(x)=4^x

Domain is the set of x values for which the function is defined.

In this exponential function, no matter we take which x values, the function remains defined for all real values of x.

Therefore, the domain of the given exponential function is All real numbers.

D is the correct option.
