Question 1

Which statements are true regarding ? Check all that apply.The domain of f(x) is (–∞, –5) U (–5, ∞).The range of f(x) is (–∞, 2) U (2, ∞).The x-intercept is at (–5, 0).The y-intercept is (0, 2). There is a vertical asymptote at x = –5.The end behavior is x → –∞, f(x) → 0 and x → ∞, f(x) → 0.
