Question 985840: I am trying to graph the function but i'm not sure if i'm supposed to place a horizontal or a vertical asymptote/where to place it, or what points to graph it at. Step by step would be helpful.
I am also supposed to give its domain and range using interval notation.
I think the domain is (1, ∞) but i'm not 100% confident
I think the range is (-∞,∞) but again, not sure. please correct me if i'm wrong.
Help would be extremely appreciated. Thank you so much, in advance!
