$\mathrm{Domain\:of\:}\:0.5^x-9\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:$

Step-by-step explanation:

Domain:

The function has no undefined points nor domain constraints. Therefore, the domain is

$...-\infty \:$

Definition: The domain of a function is the set of input or argument values for which the function is real and defined.

_________________________________________________

Range:

$\mathrm{The\:range\:of\:an\:exponential\:function\:of\:the\:form}\:c\cdot \:n^{ax+b}+k\:\mathrm{is}\:\:f\left(x\right)k\\k=-9$

$f\left(x\right)-9$

Definition: The set of values of the dependent variable for which a function is defined.

Asymptotes:

$\mathrm{Vertical\:asymptotes\:of\:}0.5^x-9:\quad \mathrm{None}\\\mathrm{Horizontal\:Asymptotes\:of\:}0.5^x-9:\quad y=-9\\\mathrm{Horizontal}:\:y=-9x^{2}$
