For example,
F(x)= 1/x, and the domain x is not equal to zero.
F(-x)= 1/(-x), and the domain requirement (-x) is not equal to zero.
F (x 2+x) = 1/(x 2+x), and the domain requirement (x 2+x) is not equal to zero.
For example, the first question,
F(x) domain,
F(-x) To apply the above fields to the (-x) in parentheses,
sulphur dioxide
The domain of g(x) is the intersection of the above two domains.
