Without Graphing, Describe the Shape of the Graph of the Function

Multiple Choice

without graphing, describe the shape of the graph of the function and complete the ordered pairs $(0,1)$ and $(1$ , $) .$
- $f(x) =6^{-x}$

A) The graph lies above the $x$ -axis, falls from left to right, with the positive $x$ -axis as a horizontal asymptote; $(0,1)$ and $\left(1, \frac{1}{6}\right)$ .
B) The graph lies above the $x$ -axis, falls from left to right, with the negative $x$ -axis as a horizontal asymptote; $(0,1)$ and $\left(1,-\frac{1}{6}\right)$ .
C) The graph lies above the $x$ -axis, falls from right to left, with the negative $x$ -axis as a horizontal asymptote; $(0,6)$ and $\left(1,-\frac{1}{6}\right)$ .
D) The graph lies above the $x$ -axis, falls from right to left, with the positive $x$ -axis as a horizontal asymptote; $(0,6)$ and $\left(1, \frac{1}{6}\right)$ .
