Ran f(X):

#### Explanation:

The domain of a exponential function is Usually

Unless, the domain is restricted this usually specified by the use of function notation in the question.

The range of the most basic exponential

Or a combination of these transformations.

For Working out range I think it is best you sketch the curve yourself or use a graphing app e.g Desmos or A Graphing calculator Like the CAS T-nspire.
