Determine the domain and range of (g ○ f)(x) if f of x is equal to 9 over the quantity x squared minus 9 end quantity and g(x) = x 3. D: {x ∈ ℝ} and R: (–∞, –3) ∪ (3, ∞) D: {x ∈ ℝ| x ≠ –6, 0} and R: (–∞, –3) ∪ (3, ∞) D: {x ∈ ℝ| x ≠ –3, 3} and R: (–∞, 2) ∪ (3, ∞) D: {x ∈ ℝ| x ≠ –6, –3, 0, 3} and R: (–∞, –2) ∪ (2, ∞)
