The exponential function f(x) has a horizontal asymptote at y = 3.
What is the end behavior of f(x)?

A.
As x decreases, f(x) approaches, but never reaches, 3. As x increases, f(x) increases.

B.
As x decreases, f(x) decreases. As x increases, f(x) approaches, but never reaches, 3.

C.
As x decreases, f(x) approaches, but never reaches, 3. As x increases, f(x) decreases.

D.
As x decreases, f(x) approaches, but never reaches, 0. As x increases, f(x) increases.
