Answer:
domain: (-infinity, infinity); range: (0, infinity)
Explanation:
The domain of a function are the values that the variable x takes.
In this case x can take any value, that is, the domain of the function is (-infinity, infinity).
The range of a function are the values that the function itself takes, f (x).
In this case, being a negative exponential, as the values of x become smaller, the function tends to 0, and if the values are larger the function tends to infinity, therefore the range of the function is (0 , infinite).
For example:
When x = -300,000

When x = 100

So, the answer is :
domain: (-infinity, infinity); range: (0, infinity)
