Consider the function $$f(x)=\sqrt{\frac{ 2 - x}{ x-8}}$$

a) Determine the domain.
Note: Write the answer in interval notation. If the answer involves more than one interval write the intervals separated by the union symbol, U.
Domain =

b) Find the vertical asymptote(s). If there is more than one vertical asymptote give a list of the $x$ -values separated by commas. If there are no vertical asymptotes type in None .

$x =$
