Question

domain, range, and evaluate exponential function
what is the range of this exponential function?
$\\{ y \mid y \leq -9\\}$
all real numbers
$\\{ y \mid y \geq -9\\}$
$\\{ y \mid y > -9\\}$
$\\{ y \mid y < -9\\}$

Explanation:

The graph has a horizontal asymptote at \(y = -9\) (the dashed line), meaning the function approaches but never reaches \(y = -9\). The curve lies below this asymptote, so all \(y\)-values are less than -9.

Answer:

{y | y < -9}
