Simply substitute the given input values and simplify to answer question #ii.

#i:
The acceptable values for x in the numerator are x%3E=-2.
The acceptable values for x in the denominator are x%3C0 or x%3E0.
In interval notation, the set of x values for the domain is the union of (-2,0) and (0,infinity).
