Answer:

D : {x ∈ R : x≠1}

Step-by-step explanation:

The domain is what values of x can we put into the function and it still works

We cannot have the denominator equal zero

x-1 ≠0

Add 1 to each side

x-1+1 ≠0+1

x≠1

The domain is all real values of x except x=1

D : {x ∈ R : x≠1}

$▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪$

let's solve for " w "

$vw {}^{2} + y = x$

$vw {}^{2} = x - y$

${w}^{2} = \dfrac{x - y}{v}$

$w = \sqrt{ \dfrac{x - y}{v} }$
