Answer: x≠0 and x can not be any value for which u(x) = 2
Explanation:
According to the question,
The domain of the function u = R - {0}
Thus if x is the element of the domain of the function u
Then , x ≠0
(v*u)(x) = v[u(x)]
Since, The domain of the function v = R - {2}
⇒ u(x) ≠ 2
⇒ Second Option is correct.
