question 123

Multiple Choice

Determine the equation of the horizontal asymptote for the graph of this function, and state the domain and range of
this function.
- $$f ( x ) = 2 ^ { x + 3 }$$

• A) Horizontal asymptote: \(y = - 3\);
• Domain: \(( - \infty , \infty )\), Range: \(( - 3 , \infty )\)
• B) Horizontal asymptote: \(\mathrm { y } = 2\);
• Domain: \(( - \infty , \infty )\), Range: \(( 2 , \infty )\)
• C) Horizontal asymptote: \(\mathrm { y } = 0\);
• Domain: \(( - \infty , \infty )\), Range: \(( 0 , \infty )\)
• D) Horizontal asymptote: \(\mathrm { y } = 3\);
• Domain: \(( - \infty , \infty )\), Range: \(( 3 , \infty )\)
