The graph of y=log⁡3(x2−4)−log⁡3(x−2)y = \log_3(x^2 - 4) - \log_3(x - 2) has a domain and range of: (A) D: {x∣x>2,x∈R}\{x \mid x > 2, x \in \mathbb{R}\} ; R: {y∣y>log⁡34,y∈R}\{y \mid y > \log_3 4, y \in \mathbb{R}\} (B) D: {x∣x≥2,x∈R}\{x \mid x \geq 2, x \in \mathbb{R}\} ; R: {y∣y≥log⁡34,y∈R}\{y \mid y \geq \log_3 4, y \in \mathbb{R}\} (C) D: {x∣x≥2,x∈R}\{x \mid x \geq 2, x \in \mathbb{R}\} ; R: {y∣y≥0,y∈R}\{y \mid y \geq 0, y \in \mathbb{R}\} (D) D: {x∣x∈R}\{x \mid x \in \mathbb{R}\} ; R: {y∣y>y∈R}\{y \mid y > y \in \mathbb{R}\}
