O domínio da função [tex3]f(x)=2\sqrt{x^2-x}[/tex3] é:
(A) [tex3]D=\left\{x \in \mathbb{R} /0 \leq x \leq 2\right\}[/tex3].
(B) [tex3]D=\left\{x \in \mathbb{R} /0 \leq x \leq 1\right\}[/tex3].
(C) [tex3]D=\left\{x \in \mathbb{R} /1 \leq x \leq 2\right\}[/tex3].
(D) [tex3]D=\left\{x \in \mathbb{R} / x \geq 2\right\}[/tex3].
(E) [tex3]D=\left\{x \in \mathbb{R} / x \geq 1\right\}[/tex3].
(A) [tex3]D=\left\{x \in \mathbb{R} /0 \leq x \leq 2\right\}[/tex3].
