What is the domain of an exponential function?
Back
The domain of an exponential function is all real numbers, expressed as (-∞, ∞).

FLASHCARD QUESTION
Front
What is the range of an exponential function?
Back
The range of an exponential function is all real numbers greater than zero, expressed as (0, ∞) for functions of the form f(x) = a * b^x where a > 0.

FLASHCARD QUESTION
Front
What is an asymptote in the context of exponential functions?
Back
An asymptote is a line that the graph of a function approaches but never touches. For exponential functions, the horizontal asymptote is typically y = 0.
