$\frac{1}{x^2-4}$

$\frac{1}{x+2}$

$\frac{1}{x-2}$ (correct)

$\frac{-3}{x-2}$

{$x \in \mathbb{Z} | x > 1 \ y \ x < 2$}

{$x \in \mathbb{Z} | x = 0 \ o \ x = 1$}

{$x \in \mathbb{Q} | x \geq 0 \ y \ x < 0$} (correct)

{$x \in \mathbb{Q} | x = -1 \ o \ x = 1$}

f(x)=3x^2-6x+ 3

f(x)=2x^2+ 3x + 4

f(x)=x^2 + 2x+ 1

f(x)=3x^2-3x + 2 (correct)
