Question

What is the domain of f(x)=3^x

Answer 1

Answer:

The domain of the function is $D=(-\infty,\infty,x|x\in \mathbb R)$  

Step-by-step explanation:

Given : Function $f(x)=3^x$

To find : What is the domain of the function given?

Solution :

Domain is defined as the set of values in which function is defined.

Since, The given function is an exponential function.

In this case there is no real numbers that makes the expression undefined.

i.e. Domain of the given function is from -infinity to +infinity

or $D=(-\infty,\infty,x|x\in \mathbb R)$

Therefore, The domain of the function is $D=(-\infty,\infty,x|x\in \mathbb R)$
