The correct answer to this question is this "domain: x > 1; range: y > 0; Yes, it is a function."

Based from the graph, it has a vertical asymptote at x = 1, so domain is x > 1 and since it has horizontal asymptote at y=0, its range is y > 0. So this concludes us to have a domain of x > 1 and a range of y > 0.
