question 396

Multiple Choice

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

• A) domain of \(f : ( - \infty , \infty )\); range of \(f : ( 2 , \infty )\) horizontal asymptote: \(\mathrm { y } = 2\)
• B) domain of \(\mathrm { f: } ( - \infty , \infty )\); range of \(\mathrm { f } : ( 5 , \infty )\) horizontal asymptote: \(\mathrm { y } = 5\)
• C) domain of \(\mathrm { f } : ( - \infty , \infty )\); range of \(\mathrm { f } : ( 2 , \infty )\) horizontal asymptote: \(\mathrm { y } = 2\)
• D) domain of \(f : ( - \infty , \infty )\); range of \(f : ( 5 , \infty )\) horizontal asymptote: \(y = 5\)
