Steps:
So for this question, it asks us for the domain of f(x) ÷ g(x). Set up our function as such:

Next, we want to find the discontinuity of this function, or the value(s) in which the function cannot equal to. In this case, we need to find the x value that makes the denominator equal to 0 (as anything divided by 0 is undefined). To find it, set the denominator to 0 and solve as such:

Answer:
With the information that we have, the answer is
, or the first option.
