Answer 1

Answer is C.
All real numbers

hope it helps

Answer 2

Answer:

C. All real numbers.

Step-by-step explanation:

We have been given a function $f(x)=3^x$. We are asked to find the domain of our given function.

We know that domain of a function is all values of x for which a function is real and defined.

We know that the domain of an exponential function is all real values of x that is $(-\infty,\infty)$.

Since our given function is an exponential function, therefore, domain of our given function is all real numbers.
