Final answer:
The question discusses a function's domain, y-intercept, and horizontal asymptotes. The function has a domain extending to negative infinity, a y-intercept where y equals 1, and horizontal asymptotes at y equals 0 and y equals 2, although there might be an error since a function can only have one y-intercept.
Step-by-step explanation:
The question asks about the characteristics of a function including the domain, y-intercept, and horizontal asymptotes. To address these, let's break down the elements:
In general, a function can only have one y-intercept, which is the point where the plot line intersects the y-axis. Horizontal asymptotes dictate the behavior of a function as x approaches infinity or negative infinity, indicating values that the function approaches but doesn't cross.
