The domain is the set of all possible x-values that the function can assume.
Given the function:
[tex]g(x)=\frac{2}{x}[/tex]
To find the domain, we have to look for restrictions for x-values.
It is known that the denominator of a fraction can not be zero.
Then, x ≠ 0.
So, the domain is of g(x) is (-∞,0) U (0, ∞).
