Use Transformations to Graph the Function $$\begin{array} { l } f ( x ) = 2 ^ { - x } + 5 \\\end{array}$$

Use transformations to graph the function. Determine the domain, range, and horizontal asymptote of the function.
- $$\begin{array} { l } f ( x ) = 2 ^ { - x } + 5 \\\end{array}$$

A) domain of $f : ( - \infty , \infty )$ ; range of $f : ( 2 , \infty )$
horizontal asymptote: $\mathrm { y } = 2$


B) domain of $f : ( - \infty , \infty )$ ; range of $f : ( 5 , \infty )$
horizontal asymptote: $\mathrm { y } = 5$

C) domain of $f : ( - \infty , \infty )$ ; range of $f : ( 2 , \infty )$
horizontal asymptote: $\mathrm { y } = 2$


D) domain of $f : ( - \infty , \infty )$ ; range of $f : ( 5 , \infty )$
horizontal asymptote: $\mathrm { y } = 5$
