What are the restrictions on the domain (u*v)(x)

x≠0 and x can not be any value for which u(x) = 2

Step-by-step 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.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
